I tried searching and couldn't find anything about it. Has anyone had any experience with the Adidas Dejada? Also, I know running shoes are usually horrible for tennis, but on another tennis forum someone mentioned spira shoes (http://www.spirafootwear.com), specifically the Genesis 2 stability shoe, as being great on all surfaces except clay. Apparently Spira shoes are banned by the International Amateur Athletic Federation and USA Track and Field Association because they have springs in them. Has anyone on this forum used these shoes?
