We love the Extra Tall and Heavy Duty Knee Walker because being on the go...while recovering from foot/ankle/Achilles injury is long, uncomfortable and very inconvenient. Stay mobile and recover better with the non-weight bearing Knee Walker equipped with locking hand brakes, rugged wheels and an extra tall, heavy duty frame that supports up to 400 lb. It's going to be a long 6-12 weeks... suffer less and move more.
