I bought these for my boyfriend who is a working chef, so he is on his feet for about 10 hours+. The arch isn't ''way too high'' as some people mentioned. It's lower than a female's arch and my boyfriend's arch matches it very well. It's form fit for your feet, curving in places where your feet naturally curve. I can see why these shoes can be ''uncomfortable'' for some if you have super flat feet+ no arch what so ever! I measured out the inside of the shoe, going from the highest point to the heel and it's 10.2 inches in length. That roughly translate to a size 8 in Nikes, Reebok, etc. I bought a size EURO 41 for my boyfriend and they're a tad bit too wide for his feet, but he has narrow feet so that explains why. . . however, thick socks fixed that problem right away. I weighed each shoe: 1 lb 1.5 oz, this might be very heavy to some compared to classic sneakers (Reebok, size 8 Mens) which weighed 8.8 oz, however the comfort ''outweighs'' that issue! See my pun there?Will update when boyfriend reports back to me about how they held up in a week's time at work. .
