Does anyone have experience with Wilson ProStaff Grand Slam Shoes? I currently wear Nike aircage (the blake model) for non tennis (as I always seems to sprain a little when i try to play in them). My regular tennis shoe is the Adidas Barricade IV in size 10 and they fit well. a little snug in width but length is great. I am trying to figure out if I should buy wilson prostaff grand slams online in size 9.5 or 10. my reebok size has always been 9.5, nike, 9.5, adidas 10....but i havent work wilson shoes before. advice on prostaff sizing?
