I work in events. The first day I wore these to work i was on my feet from 10am to 4am. 18hours and they did not miss a beat.
I really wanted to like these shoes. I have bought quite a few shoes from bprimal before, so I was confident the sizing tool was accurate for my size. I bought the recommended size, but when it arrived it looked too big and felt too roomy on my feet. I returned it for the smaller size. When this arrived, they looked really nice on, but the toe box seemed too shallow. So I applied some leather stretcher and all seemed good. They are ok for short walks, but on longer walks, I experienced pain and bruising in my 2nd toe and toe nail. It turns out the be lenka shoes are a more extreme barefoot shape than my foot, as my big toe is shorter than my 2nd toe. They are lovely shoes, and I do still occasionally wear them, but disappointed I couldn't use them the way I wanted to. So, check the shape of your feet before you buy these!
