My 80 year old uncle needed needed new walking shoes after having his knee replaced.  Distance and size constraints made it worthwhile taking a chance on buying shoes off the web and having a next day Saturday delivery via Amazon Prime a very viable option.  If it didn't work out I had an extra day to run from store to store looking for the right type, size, and price.  He got the shoes the next day, wore them for several days before therapy, and continues to wear them comfortably.  He liked the color and the velcro flaps especially. HAven't seen them in person yet, but he seems thrilled with them.
