After reading up on the Glycerin 8s, I enthusiatically ordered a size 12, my usual size. In less than a week, I had a black toenail from my toes rubbing up against the front of the shoe. The shoes are back in the box and in the closet. They seem to be about 1/2 size smaller than Asics, which I normally wear. I guess, I need to stop shopping on line and try shoes on before buying or just stick with Asics, which are hard to beat.
