These definitely run small. I usually wear 7.5 and 8 so I went with 9 on these. Size 9 fits just fine but there is no room for socks. They make your feet look large so they work better for athletic purposes.

I bought the pair awhile ago but wore it hiking for the first time last weekend. They are amazing on the extremely rough terrain. The thick soles and shearling padding acted as an excellent cushion between my feet and rocks, gravels, and whatnot. The only issue I had was that the twigs, leaves, and sand kept finding their way through the not-so-tight opening into my boots. I had to stop every half mile to take the shoes off and unload the debris. It was a longer hike but my feet did not hurt or get tired as when I wore the traditional hiking shoes (the type that has a stiffer sole and lace-up instep). Maybe it is just me, my feet seems to be much more efficient on the trails when they are not tied down and boxed up in traditional boots. The ability to flex and stretch while walking makes for a more comfortable hike.
