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 ourPrintable Size Guidefor 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 thesizing chartprovided 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.

Natural Foot Shape Restoration
Our mission is to help you restore your feet to their natural, primal shape, reducing pain and improving overall foot health.
Immediately comfortable and great quality. These boots are so light and easy to wear all day. Waterproofing can make feet sweat so good moisture wicking socks are a must. A little hard for me to slip on because of my high insteps but much easier compared to other brands I’ve tried. Definitely use the online sizing guide as these had me in one size up from my normal size and they were perfect.
These are my second pair of Lems Primal, and they do not disappoint. I’ve been wearing barefoot style for several years and these are super comfortable, nice wide toebox.
The Zens are just perfect. I’ll be trialing in Europe this September and October on my Eurail tour of Germany, Switzerland, Italy, France, England and Belgium.
I'm very happy with my Boulder Boots. They look great, they feel great.
A fairly minor comment:
It seems that unlacing the boots feels like more work than necessary to get enough 'openness' to get my foot out in thick socks, and getting m y feet in. Maybe the gusset (or whatever it's called) could be more generous, so getting feet in and out is easier? I'm a bit old...
I have unsubscribed from your email list, still love the boots, but unlikely to buy more, though if anyone who asks me, I'll speak well about them/ Cheers.

Online sizing feature worked perfectly. Great shoes!
Ordered these shoes using the online features on the website to calculate sizing, I was anxious how accurate it would be buying shoes without trying them on.
They were posted Monday and delivered Thursday.
Put them on and walked a lap of the block. I kept wiggling my toes as it was such an odd sensation having space to do so. Felt like I was wearing an old pair of shoes. Super comfortable and I love the colour.
I really like them.
