If you order from the Running Warehouse (the link in my first post) your order comes with a pre-paid return label. If they don't fit just put them back in the box no questions asked and your original purchase price is refunded in full. You have the option of returning for refund or having them send something else (different size, item whatever). Their size availability varies quite often but when you see the size you want to try just order it up and see if it works.

I almost forgot. Shipping both ways is free from Running Warehouse. So the price for the shoes is all you pay and if you need/want to return them you are out zero.
