I get TONS of compliments on these. They run a bit big (I normally wear a women's 9 in boots) and the calves are a bit snug, but amazingly comfortable. I wore them for almost 9hrs straight pretty much right out of the box. Heel is totally solid and comfortable, lots of cushioning.

If you have particularly wide feet, or larger calves, I would not recommend. Or see if you can find a store to try them on first.
