First off, these shoes look great, they are high quality and the sole has a lot of support. The inside is a faux fur so they are very comfortable in bare feet. I changed out the red laces with grey and I really like the look.
I'm not sure if they were designed to be worn with bare feet but they are wayyy too small to wear with socks. When I first got them I ordered a 10.5; I wear that size with Nike, Asics, and Lakai's so I am sure that is my size. I returned them and ordered an 11 hoping it would be fine, but they are still too small. The left one is ok but the right one is really tight.
I'm not sure if its just me but I have read the same thing in other reviews.The problem is the width on the front of the foot. Standing in them for extended periods crushes the side of your foot. I've given up on wearing them with socks and they have become summer shoes.
My advice, get .5 size up if you plan to wear barefoot. Get 1 size up if you want to wear with socks.
