The Ivalo has been a popular choice since its first version. Lighter than their looks might suggest, they offer great winter performance. As is typical of Icebug shoes, the studs are pushed just a bit inwards when walking on very hard surfaces, enabling the base rubber to come in contact with hard flooring. Note! Studs harm many floor materials - be aware of what you're walking on. The rocker structure offers a great striding feel. The Ivalo is a great choice for everyday use as well as hiking, whenever you need the traction offered by studs. - *Narrower fit than the average Icebug, choose one size bigger* - Sprayproof front zipper - Shaft surface material made of strong ripstop fabric, 100% recycled polyester, and dyed with the water-saving, chemical load decreasing solution dye method - Insulation made of 100% recycled polyester - Fleece liner made of 100% recycled polyester, and dyed with the water-saving, chemical load decreasing solution dye method - Lower reinforcements are 100
