Wonderfully supportive!
I have many feet issues, including a hammer toe and plantar fasciitis. I have special orthotics that go in my tennis shoes, but was lacking a sandal to wear when my feet are hot. These came a bit large, but I threw them into the dryer with a large towel to absorb the noise. After about 7 or 8 minutes, I removed them, made sure they weren’t too hot, then wore them 20 minutes at a time. They shrunk to the correct length 9.5 instead of the 10 and they began molding to my feet. I did this several times in the first day. They fit great now!
