Wow, these are so comfortable! Instant keepers. I buy size 11
shoes, but my feet are closer to 11 1/2, so I ordered an 11 and 12. The 11's work fine. These are true to size. I have pancake flat feet and these seem to have decent support to me. All I know is they feel great on my feet. I bought them in white and immediately went to Zappos to order a 2nd pair in black, but they weren't available. I had to go somewhere else, which is a shame, because Zappos has the best service of any company I've encountered on the net. I would actually forgo a 20% discount or whatever from another site to order from Zappos.
Walking Cradles is a new brand for me, so I intend to review these again in the future regarding long-term comfort and quality, but I'm impressed.
