By means of a more flexible sole, walking on fresh coatings is more comfortable. POLYPLAN Spiked Shoes have a polypropylene body with grooves at the bottom side of the sole. Thereby the spiked shoes adjust better natural movement when walking. The POLYPLAN Spiked shoes are delivered with hardened pointed steel spikes, 30 mm long ~1 3/16 inch. Due to the straps with velcro fasteners the spiked shoes can be easily fastened under any shoe.
