Woof Wear Mud Fever Turnout Boots Black/Grey The Woof Wear Mud Fever Boots are both breathable and innovative, sealing the leg from the knee down to the base of the heel. This prevents mud from getting onto your horses legs and allows the freedom to turn out whatever the conditions. Around the cannon bone, the fabric is waterproof and breathable, preventing overheating. The close-fitting hoof capsule features Kevlar reinforced heel protection, whilst the shaped PU strike pad provides a degree of brushing protection. The Mud Fever Turnout Boots feature a \\\'Submarine Hoof Capsule\\\'. The Capsule \\\'dives deep\\\' beneath the heel bulbs to prevent the boot from slippage or riding upward and provides added mud protection. Designed from a loose-fitting, waterproof and breathable fabric, the Mud Fever Turnout Boots allow air to circulate around the leg. This creates a micro-climate preventing warm and damp conditions which mud fever loves.
