I ordered 10.5 initally was sent a 10 in a10.5 box but the order was corrected immediately. I wouldn't say these were the most comfortable shoes. I got them to replace my old bear paw boots. Arch support is good, however the top of the shoe pulls when walking. I imagine the seam will probably give way at some point sooner than later. Was hoping for a better shoe. I just ordered sorrels because on my trip to Canada they were the staple. It's just a 10.5 fits better than 11 oh well I will double up on socks!
