One of the best boots, it fits comfortably with just three fastenings, it inflates easily with the double air bladders providing stability to the foot and the heel has a soft EVA sole to absorb the impact from walking, making the use of such a boot relatively more comfortable. Traverse Air Walker by Aspen Medical Products, the next best option is the Airstep® Walker, the REBOUND PNEUMATIC WALKER, and the AIR SELECT PNEUMATIC WALKER, but unfortunately, when I needed to purchase it, none of the FULL ROCKER BOTTOM options were available in the market. However, the Traverse Air Walker leaves you very satisfied with its use to the point that you don't need something much more expensive, at least for small metatarsal fractures, as it closely resembles the ergonomic design of the AIR SELECT.
