Nice wide toe, light-weight, sufficient arch and snug around my high instep, but not tight. I don't run, but have a lot of foot issues. I wear these as my 'house shoes' instead of slippers that don't have enough support or sport shoes that can become heavy by the end of the day. I can see that if I did run, these would be great, because they don't slip at the top or rub on the back of the heal, and they have enough room at the toe for pressure. Great shoe and will buy again!
