The Mongrel 805025 Black Riding Boot is a popular and well-constructed premium leather boot that features a rigid instep shank, making this the perfect riding-boot. This is a fully lined, good-looking boot that could also serve well as an everyday work or dress boot. The OrthoTec PU Air innersole is a deceptively simple but long wearing and comfortable design. The air blown PU assists in air circulation and moisture control, while giving the wearer maximum comfort underfoot.
