For top-notch style, comfort and warmth, get the Peak lace-up boot from Earth. Waterproof nubuck leather upper with cross-stitch accents and faux-fur lining and collar for added style. Adjustable lace-up closure with d-ring lacing system for a super-secure and comfortable fit. The most defining feature of Earth Footwear is a slight 3.7 incline - a unique design that positions the toes 3.7 higher than the heels. The natural angle re-distributes body weight - strengthening, toning, and engaging muscles throughout the body. To complement the 3.7 incline, all Earth footwear features reinforced support through the arch. The arch support maximizes the effectiveness of the heel design in promoting a very natural walking motion. Inside all Earth Footwear, a form-fitting footbed provides exceptional comfort with BioFoam cushioning. The proprietary material molds to the shape of the foot, displacing and absorbing shock with each step, and is environmentally-considerate, using 70% recycled content. Textured rubber outsole adds lightweight durability and helps reduce step shock. Shaft: 14 in Circumference: 15 in Weight: 1 lb 14 oz Product measurements were taken using size 6.5.
