True to size, but the toe box was too tight, almost elastic- it was alright as long as I was walking, but as soon as I sat, it would slowly tighten and cut my blood supply off. I used it for 5-7 times at the gym, and instead of providing cushioning to my feet, it somehow induced toe pain- the sole is too stiff.

Great looker, yes, but I returned this and went for the Gel Kahana 4 instead, which has been a winner!
