State-of-the-art jumping fetlock boots featuring the "Air-Shock" cushioning system made up of pressurized gas in a tough and flexible polymer bag. The air bag remains flexible and will not degrade over time like foam-only solutions can. The air bag compresses to reduce and spread the force of impact and then returns to its original shape and volume. The air cushions are lightweight, durable, and last the life of the boot. Specially designed strike guard to dissipate impact, neoprene lining, and vented air holes. TPU plastic.
