Thanks for the suggestions. I bought the Saucony Triumph shoes just because they are so comfortable and support my feet. I was at an athletic apparel store, not a department store, and tried on several pairs. I'll look into the option of squash shoes next time I'm near that store and if they have a pair that are as comfortable and supportive as the Saucony Triumphs, I'll get them. I'll also ask the saleslady there who is very knowledgeable about the shoe inventory if she has a recommendation.
