The new Oxy breathable tendon boot has a radical design that provides the utmost impact protection and works with a ventilation system to allow the boot to breathe, keeping the leg cool. It is packed full of innovative features such as Woof Wears new shock shell technology, which is a raised panel positioned down the centre of the tough PU outer. This creates a gullet, which does not contact the leg and forms a pocket of air to protect the delicate tendon by transferring impact around the boot.
