Shortly after I had a major problem with my ankle, I saw a recommendation for the TR 2 model in a magazine at a doctor's office. They are well cushioned, very supportive at the ankle, and have room for your toes. I wish they had more colors available in more sizes, though. I found them so comfortable that I sent a pair to my 81-year old mother, and she feels much more stable in them than she did in her other similarly priced shoes. The physical therapist who treated my ankle injury told me to replace my shoes every 6 months, so I just upgraded both my mom and me to the TR 3. We are both happy walkers!
