Winter barefoot ankle boots Vivobarefoot Tracker Decon FG2 M have an interior made of premium Woolmark® wool in the ankle area, which ensures breathability, thermal comfort and easy putting on. The separate leather part fulfills a protective function here and allows maximum flexibility in all directions. The new, multi-terrain sole offers even better grip on the road and off-road. Thanks to the first-class materials used and the cut worked out to the last detail, you will fall in love with the Tracker Decon FG2 the first time you put it on. * upper material: premium leather and breathable Woolmark® certified merino wool * lining and insole: textile * sole: 2.5mm rubber sole with 4mm multi-terrain pattern, with patented puncture-resistant protection. An ultra-thin, abrasion-resistant, extra-flexible, non-slip sole that allows you to perfectly feel the surface you walk on every day. * lacing: laces * inner removable insole: yes, thermal insole * loop in the heel part and on the tongue * elastic cuff * reinforcement around the ankle * vegan: no * recommendation: Inner insoles of VIVOBAREFOOT shoes, mainly used on cold days to maintain thermal comfort. We also recommend them in the first days and weeks of walking and running in barefoot shoes, so that the feet gradually get used to the transition from classic shoes. After that, just like on days with temperatures above freezing, we recommend removing the insoles to enhance the feeling of walking barefoot. * leather shoes
