btw MD, try www.tenniswarehouse.com. You can order multiple sizes, keep the ones that fit and send the others back no questions asked. no matter how many pairs you order shipping is like $6. In your situation where trying them on is a must, this works out great (I have the same problem as you, have to try them on first, luckily midtown NYC gives me a better chance to go to a brick/mortar store and then order online, but i've been buying from tenniswarehouse for years, works great)
