I've just worn the Boulder boots daily for over two months. They were comfortable from day one and were also great as a slip on boot camping, with the laces undone I could still walk around fine. I never need to lace them firm and my foot moves freely about but with sufficient support. I was uncertain how the grip would be, but they were better than any other hiking boot/shoe I have ever worn including vibram. They had a good work out in granite country and the grip held even on wet, smooth rock surfaces. I found I was at times skipping down slopes when others were taking every step cautiously. I never had any skeletal/ joint issues, knee in particular which I used to have before transitioning fully to barefoot and zero drop. I made some grounding straps out of an old earthing mat that I held in place with a piece of velcro and it dropped my body voltage down to almost zero just via the leather upper with no actual direct skin contact needed. The only thing I will mention is that the soles have been coming away from the uppers. Faye followed up on my email right away and they have been replaced under warranty. Generally I would look elsewhere next time if that occurred but it doesn't appear to be a common thing, but also the boots are that good that I would still have to buy them again, providing the sole can be reattached. I thought the Primal 2's would be my shoe of choice fo general hiking but I found the comfort and grip of the boots to be much better. They were superb with temperature regulation from sub zero to highest temp so far 27degrees c. Lastly, usually during or at the end of a walk I just want to take my boots off, with the Boulder boots I would be happy to wear them to bed.
So far very comfy :)
Extremely comfortable boots and excellent customer service
Even though I consulted with company prior to choosing size (and went up recommended half size) they were still too small. I would recommend going up at least 1 size (possibly 1 and a half).
Boots came quicker than expected, they were super comfortable and good quality but because of the wide toe design look quite bulky and masculine. I returned the boots for a full refund minus shipping costs which were returned from PayPal. An easy service and no questions asked. Great customer service.
