I'm disappointed in the Solstice so far. I wear a solid US 10, yet the 40 was too small and the 41 too big. I opted for the 40 with ultra-thin socks. I got huge blisters on the back of one foot the second day of wearing. I looked at the interior of the shoe and the leather was completely rough and cheap looking. One shoe was great, the other clearly of inferior quality. While the heel is supposed to slip on Dansko clogs, this particular style has a narrower Achilles area which is horribly designed. If the shoe is on the small side--blisters. If the shoe is on the big side--flopping. Very disappointed, as these are the most attractive Danskos I've seen.
