These shoes are like stepping onto a puffy cloud. They are so cushiony. They blow my Merrell Encore Groove shoes away! I wear them on the treadmill when I walk. I also plan to wear them on a trip to Europe. I have the black ones. They are kind of geeky-looking, but very comfortable! I thought that the "shape-up" claims were just a gimmick, but when I read about these improving your posture, I thought I might give them a try. I do feel like they align your body more correctly. I ordered 1/2 size larger due to the reviews. I probably could've fit into my normal size, but the laces are really tight when they come, so I'm glad I ordered a larger size. I feel like this may have turned me into an MBT-convert for life!
