I good place to shop for your shoes whether you are out on the trail or at home is Zappos. They have free overnight shipping and free return shipping. You can order as many pairs of shoes as you want, try them on, and return them for free, if they don’t work out for you. I once ordered 5 pairs of shoes and returned all of them with no hassles. You need to be able to access the Internet and a printer to print the return labels.
Their phone number is 1-800-927-7671. They take orders 24/7 and they will ship, Fed-ex, UPS, or USPS.
