I am so impressed by the rugged bottom sole of this hiking shoe. It keeps me from slipping down gravel trails. I feel so more stable in these shoes than I have felt in any other hiking shoes/boots I've ever owned. I did want to comment on the size comments I have read. I wear a 9.5 and bought these in a 10, thinking they ran big as many have said. But my feet swam in the size 10. I am ordering a 9.5 now as my size 10 were burned up in my house fire. The Keen sandals I would recommend ordering a 1/2 size up, but not this particular shoe/boot - order your normal size.
