This is an awesome low cut with a knitted body so it’s extremely comfortable and lightweight. Excellent indoors but are great outdoors as well. Lace ’em up tight and they’ll “cling to the foot like a second skin!” Reinforced with Dyneema yarn, which has a strength-to-weight ratio that is 15 times stronger than steel. Due to the way the material is knitted, only the inside – made of iVN Best-certified, mulesing-free and climate-regulating merino wool – touches the foot. The outside is made of abrasion-resistant polyester. It also has a removable insole that makes it easier to air and dry, as well as a microfiber pad on the heel for an optimal fit.
