After doing much research on running shoes, I decided on this one and ordered it. Much to my disappointment, when the pair arrived, they were so small that I could not begin to get my foot into the shoe. I ordered the size I normally wear (and there was no warning about buying a larger size), but they seemed about 2 sizes smaller than the label indicated. Amazon was very good about refunding my purchase and shipping, but I was afraid to order the shoe again because I had no real idea what size to try next. I plan to buy the shoe somewhere that I can try one one first.
