SIZING & FIT GUIDE

Our Fit recommendation for this shoe based on customer feedback: We recommend ordering your normal US size for this model. If you need additional volume, you can remove the insole.

If you don't know your normal US size, or would like to double check sizing for this model, please use the sizing tools we have provided here like this:

1. Print out our Printable Size Guide for this model and stand on it - making sure your printer is set to 100% Scale. Choose the size where your longest toe finishes. If you are on the line, consider if you will be wearing thick socks, or prefer to have less or more space in your shoes and choose accordingly.

2. Use our Strutfit online sizing app to check your feet measurement and it will tell you what size to order - Click on "WHAT IS MY SIZE?" above. You will need an a4 sheet of paper and a smartphone for this. Once you have done this once, it will also tell you what size you need for all the other shoes on our website as you browse through other models.

3. Use the sizing chart provided which shows the insole length and width of the shoe which you can use to compare the measurements against another pair of shoes that fit you well. Or you can compare them with a sizing chart from another brand and work out your size that way. This is not a fool-safe way though, as the volume and material in the upper of the shoe can also make a big difference to the fit so best to use this in conjunction with one of the other sizing methods.

We don't recommend manually measuring your feet to work out sizing, as in our experience most people measure incorrectly without the use of a proper tool such as a brannock device.

Comfortable boots

Great boots, quite comfortable particularly with socks as the ankle bit can rub a bit. Two things though. They are harder for me to get on and off than I expected even though fitting perfectly when on. Also when ordering I did not expect swede and would have preferred regular leather as I could polish them.

These boots are lighter than my runners! I used the printable size chart and it was bang-on. Only worn them for a week at work, hoping to get a year out of them (they are twice the price of my usual Blundstone boots, but ten times more comfortable), so can’t comment on durability yet. If you are looking for a boot that is as comfortable and light as runners, you’ll be impressed. Looking forward to the Sydney store opening up to try other models.

Helen K.

This is my first pair of "minimalist" shoes and I LOVE them! They are so comfortable.
I read some reviews before ordering, and followed advice to order a bigger size than usual. I usually wear WUS8.5, but order WUS9 and they fit perfectly, plenty of room, but not too loose.
I've barely taken them off since receiving.

Fleta R.

We have recently had a four week holiday to Norway and the UK. We took one pair of shoes each. The Lems waterproof Chelsea boots. We took the advice from many comments and ordered a size and a half up from our normal shoe size. It was a good decision as they fitted perfectly. These shoes took us through snow, ice (with cleats), mud, puddles, pavements and streets. They are truly waterproof and honestly, the most comfortable shoe we’ve ever worn. I have them on as I type this and am just about to order another pair so I can have work Lems and stepping out Lems. Do not hesitate to buy this shoe!!!!

Great boots

I have blundstones and vivo barefoot gobi 3’s and find these a great mix of the two. Usually travel with the gobi’s but find my feet get sore after lots of walking. These seem to fill the spot in between. Followed the advice and went up a full size. Perfect fit!

Lems - Chelsea Boot Positive Review

I have tried many boots and returned them all. I have a long and narrow foot so find that the bigger size shoes are far to wide for my foot. I had to go up a size in the Lems Chelsea boot as they are small. However, I put an extra innersole in and wear two pairs of socks and I'm really liking them. This is the first pair of boots that I've been able to buy and wear in years. I'm really happy with them and would definitely consider buying another pair in a different colour.

Impressed

I am really impressed with this shoe. I also wear other brands mainly vivo but I need something waterproof and closed in for travel. I wore these three times last week through rain and my feet stayed so warm and dry. I feel there is more tread then my usual barefoot shoes but they are a more robust option and should fair well on my future trip overseas. I like that I can pull them on and off easily. I have a very narrow foot and there is a lot of space in these and the right amount of snug around the ankle. I will definitely purchase this brand again. I sized up as recommended which I highly recommend.

Perfect boot!

My kids were so happy with the brown lems but are over the moon with the black waterproof ones! They are well made, comfortable, and they look amazing. We haven’t tested them in rain yet but the weather is turning just in time. Keep these in stock! Thank you

Michelle H.

Great all round boot which I believe will meet my needs when travelling to Scandinavia soon. I do have a very high instep which makes getting the boot on a little challenging but once they are on they are VERY comfortable. I did go one size up. The printable size chart helped. Cheers

Love these boots. I do not want to put any confining type of shoe on my feet now. They look great and the oiled surface is perfect for the busy bar work I do. A quick wipe over and they look brand new again.

🌱 LEMS SHOES SPECIFIC FAQ'S

I’m not sure which style to choose. Do you have a comparison chart?

We get it — with so many great styles, it can be tricky to pick just one! To make life easier, Lems has put together a handy chart that compares all the styles side by side. You’ll find details like weight, flexibility, traction, and stack height, so you can see exactly how each shoe measures up.

Check it out on our Lems Sizing and Fitting Info page.

How do I choose the right size?

The size chart for each product shows the inner length and width of each shoe model. Your toes should always have space to move freely: we recommend approx 12mm of space in front of your toes (no less than 6mm and no more than 18mm). Refer to our comprehensive Find your Perfect Fit page for guidance on exactly how to measure your feet and choose the right size. 

Still not sure? Reach out to info@bprimal.com — the team is always happy to help.

How Wide Are Lems Shoes?

Lems Shoes come in 3 Natural-Shape™ widths: MEDIUM, WIDE and WIDEST, depending on the model. Please refer to our Lems Sizing and Fitting Info page for the comparison between models.

What if you are out of stock in my size?

Some of our Lems shoes are very popular, and they sell out fast! If we are out of stock in your size and you are unable to preorder it on our website, please reach out to our team at info@bprimal.com. We are able to preorder Lems shoes, so we can help you place a preorder.

*Please note, dispatch for preorders is typically 3-4 weeks.

Should I choose a shoe with an IBR outsole or a full rubber outsole?

It depends on what you're looking for in performance and durability:

  • Injection Blown Rubber (IBR) outsoles are exceptionally lightweight, flexible, and comfortable—ideal for everyday use and casual activities. However, this lightweight design means they’re slightly less durable than full rubber soles, and may wear down more quickly if used on rough terrain.
  • Full rubber outsoles are more robust and rugged, offering better traction and durability—this makes them great candidates for hiking, trail running, or extended outdoor adventures.
How Can Lems Shoes Benefit You?

With their unique design, featuring a wide toe-box, flexible material, and zero-drop outsole, Lems shoes have the ability to aid in correcting common foot ailments, increase strength in the lower extremities, allow for greater balance, and help realign your posture. Plus, they are just down right comfortable.

I Have Never Worn Barefoot Shoes; Will Lems Shoes Work For Me?

Yes! You may experience some discomfort at first, but, know that this just means the tendons and muscles in your feet adapting to the lack of support that most contemporary shoe companies incorporate into their designs. This should subside over a short period of time.

We typically recommend wearing the shoes sparingly at first, and then progressing to longer durations of wear. It’s all about the transition! Trust the process.

What’s the difference between the Primal 3 and the Primal Zen?

The Primal 3 and Primal Zen are both everyday barefoot shoes with plenty in common — zero-drop, a wide toe box, breathable mesh uppers, and all-day comfort. Here’s where they differ:

  • Primal Zen: More relaxed fit with an attached tongue, firmer heel, slightly higher stack height, and an athletic look.
  • Primal 3: Snugger fit in the arch and heel, detached tongue for flexibility, softer heel, and a sleeker, more minimal appearance.

Both are great for everyday adventures — walking, commuting, or kicking around town. Go Zen if you prefer sporty style, or Primal 3 if you like a minimalist look.

Which waterproof boot is best for me?

Lems has several waterproof boot options, and to help you choose, they’ve created a comparison chart: Lems Sizing and Fitting Info. You’ll see all the key specs side by side.

Insole specifications - what is the difference?

Some of the Lems insoles are cork, and some are poly. All shoes are sold with the insoles inside the shoe - but they are interchangeable and can be easily trimmed with scissors if needed.

For more information on each insole thickness, go to the product page for each insole, click SPECS, and read more.

Do you have any shoes made specifically for women?

Yes! The Laguna is designed just for women, with a narrower heel collar and a slip-on style that’s sleek and versatile. For a slightly less wide option, the Trailhead has a D-width toe box — narrower than most other Lems styles.

Are Lems heavy-duty work boots?

Not quite. Lems boots are lightweight, flexible, and shaped to let your toes splay naturally. They’re not designed for the heavy-duty durability of traditional work boots.

Will Lems help with bunions, hammertoes, plantar fasciitis, or other foot issues?

Many customers with these foot conditions have found relief in Lems thanks to the roomy toe box, flexibility, and zero-drop platform. That said, it’s always best to chat with your doctor to see if Lems are right for you.

I have flat feet. Can I wear Lems?

Absolutely! If your flat feet feel good with minimal arch support, wide toe boxes, and flexible soles, Lems could be a great fit for you. Many people with flat feet find them super comfortable.

Can I Wear Lems Shoes With Custom Orthotics?

All of Lems shoes feature an insole within the shoes that can be removed to allow room for almost all custom orthotics.

Are Lems insulated for cold weather?

Lems shoes and boots aren’t insulated or temperature-rated. But pair them with warm socks or insulated insoles, and you’ll be adventure-ready even when it’s chilly. We recommend pairing with Bprimal Merino Wool toe socks to keep your feet cozy.

How Would You Recommend Cleaning My Lems?

For shoes featuring mesh or canvas, use lukewarm water and mild dish soap to hand wash your shoes. Please allow your shoes to air dry completely over 24hrs before wearing.

*Please note: If you soak your shoes in hot water for a period of time, this can cause the dye fixative or mordant to be removed and can result in the colour running. As Lems shoes have a rubber outsole, high heat washing can also shrink the shoes, so Lems do not recommend putting your shoes in the washer. 

For leather shoes, use a suitable leather care cleaner To dry your shoes, just leave them out at room temperature and not expose them to heat.

Do Lems contain latex?

Some styles do. Here’s the breakdown:

  • Contain latex in the elastic: Chelsea Boots, Drifters, Laguna.
  • Contain latex in the rubber soles: Boulder Summit, Outlander, Boulder Boot Grip, Kourt Grip, Primal Pursuit.
Do I Need To Order A Size Larger To Accommodate The Correct Toes?

In most cases you should not have to order a larger size to allow room for Correct Toes. We recommend removing the insole when you are wearing correct toes, to create extra volume in the shoe if you need it.  If you have a very wide foot you may have to order one size up to accommodate the Correct Toes.

What Is There Is A Problem With My Shoes?

We always look to be reasonable and fair in resolving any problem you have with your order from us. Please email info@bprimal.com with your order number and photos.
