Some adidas and nike shoes have a six month outsole guarentee. I'm not sure if other brands do this or not. Anyways, I was wondering why some have it and some don't? Are the ones that have it made with a tougher outsole or are they just higher priced shoes and you are actually paying for that guarentee in the price of the shoe? It'd be nice to wear out a pair of shoes every couple of months and get a brand new pair!!
