I found these boots to be unwearable. The seam created where the stiff plastic upper meets the softer toe cap creates a friction point on the top of the big toe when the boot flexes. I purchased the proper size and wore them around the house for several hours. But after a few hours of actual use, both my toes blistered. It's too bad, these boots offer great support and warmth, but they're just too painful to use.
Thank you Backcountry for a great return policy!
