This afternoon I went to Step, one of the biggest sporting good shops in Japan. I was amazed at the variety of lightweight trainers and racers especially made by Asics and Nike. The problem is that the biggest size they make is usually 28.5, around size 10. I found one cool nike racer which only went up to 26.5. I wonder why nike and asics don't sell those models in the U.S, and why they don't make bigger sizes. I suppose they don't think they would sell enough but obviously it seems like there is a growing market for them.
