Promedics Airstep Walker (Barton under Needwood DE13)
My son has recovered from his ankle injury. The hospital issued protection boot (Promedics Airstep Walker) in the photo is not needed anymore, hopeful. If it can be of any use to anyone, it is free. Although its size is XL it has adjustable straps and should fit smaller feet.
