I read a lot of reviews before purchasing these boots.

One reviewer mentioned loose fit at the heel (which I often experience with many shoes) but if you were thicker socks there is NO issue with the looser heel fit (it did not flop or slip)

First wear I ran through a local department store (which is a good test for me, since my feet usually kill me in stores).. My feet were happy. The cushioning is great, the souls do not slip.

The next day I took them on a trip with a lot of walking & hiking (including steep inclines up a waterfall)... again no ache, no blisters, no issue.. and no slipping (great grip).

These are warm but not to the point your feet feel overheated or uncomfortable.

These boots feel broken in when you get them, not stiff, but not as extreme-loose as a slipper, just perfect comfort. These are so comfortable I would wear these exclusively.

I wear between an 8 1/2 & 9 (39-40 Euro) and the 9 were excellent (they would be "floppy" with thin socks, but a decent pair of hiking socks and they are great --HIGHLY recommend smart wool hiking socks). --(side note I do have wide feet--but not to the point "wide" widths fit right.. I am stuck somewhere between, I often refer to as duck-feet since I have a wide front, high instep & narrow heel).

LOVE these boots.

Another reviewer noted they are not stylish, I have no idea what that meant, since style is relative... they might not be "trendy" but they are cute and above all comfortable.

PS.. VERY easy to get on & off too!
