Bring on the cold! The newest Mountain Horse winter boot features a black faux fur lining. Very fashionable and extremely warm! New and improved elastic along side the YKK® zipper has 50% more stretch than the original Mountain Horse elastic, allowing a more comfortable fit for many more riders because of the super stretch. A brand new, specially designed outsole has slip resistant and dirt repellent tread zones which will give riders enhanced grip in the irons. Reflective inserts at the back of the boot provide visibility during evening hours. An ergonomically designed removable EVA insole has soft Nylex® lining for all day comfort and a built-in steel shank that provides increased stability while walking or riding. The heel part is fitted with the shock-absorbing IPS™ system to reduce shock impact while walking. Material: PU/PVC
