Bought these for my teenaged daughter and was very happy to see she could adjust the velcro closure over the instep. I did try them on as well b/c I was curious how the sensory input from the footbed felt. Very comfortable, and provides an ongoing stimulation/massage to the entire sole of the foot.
She's very happy to wear these almost daily and we enjoy that we didn't have to pay more than local retail for them! Would definitely consider getting a set myself, once we live somewhere where snow isn't a daily concern in shoe choice!
