love this shoe. Very comfortable. I need a wide toe box and a snug fitting heel and this shoe is perfect for me.
I have another pair of Ahnus and the fit is similiar. My other pair of Ahnus are not waterproof and the size 9 was perfect but I did have to get these in 9 1/2. But I noticed that I had to get the half size bigger in all the waterproof styles I tried on. But even then the Ahnu is the only one that did not put my toes to sleep.
I have been putting some miles on these and they continue to feel good. I have had injuries to my achilles and a crushed foot as a teenager that makes it esp. Hard to find well fitting shoes I can walk in.
So if you need a shoe with good ankle and arch support, plenty of toe room, and that is not a sweatbox, these are great shoes.
