hello,I'm pretty new,but I do know personally that sketcher is an excellent tennis shoe.My son got stuck in concrete culvert pipe,and the fire deptmartment (he was wearing sketcher),cut his tennis shoes with jaws of life.(didn't free him),so they had to blow up the pipe in order to get him out.When all was said and done the fire chief told me the only reason he was stuck was because of that tennis shoe..he told me to write to sketcher and tell them they are best tennis shoe on the market. maybe if you conatct sketcher they can give you some info on where to find a supplier.oh and sketcher got alot of free publicity from that because the town made a big write up in the paper over how even the jaws of life could not destroy that tennis shoe.Feel free to share this story with any of your customers who question the value of sketcher.
