I was replacing an older pair and these were authentic OBOZ even though I paid 1/2 the price I paid for my first pair ant SCHEELS. Everything is as described color, fit, & style. I LOVE OBOZ because they have good arch support. I wore them all day the first day without any issues. I have a wider foot but the 8.5 fit perfectly. I do wear them with merino wool socks not heavyweight hiking socks. If you have very wide feet I would say these might not be for you. I am a solid 39 but in US sizes I can be an 8 or 8 1/2. I hope this helps someone trying to figure sizing. I do spray them with a water proof spray for extra protection but the shoes hold up well.
