I am about to buy a pair of lotto soccer shoes. ( http://www.soccer.com/IWCatProductPage.process?Merchant_Id=1&query=orange&Ne=234&N=4294960675&Product_Id=521896 ). i wear a size 9.5 or 10 in adidas and am wondering what size to get in lottos because i know some brands of shoe can run small or larger than others.
