EVA foam is familiar for many from running shoes. It is light, it absorbs shocks and insulates extremely well. These Niseko 3.0 boots are designed for a similar look to working and fishing boots used in Japan. Compared to the 2.0 version, the 3.0 version features updated sizing, so it's worth checking the size chart carefully. The collar fabric is more durable, and the lining material is more breathable and quicker-drying. As a nice bonus, the insoles are now removable. This boot model is a great choice for cool and cold conditions, for outdoor hobbies and work such as ice fishing, nature photography or hunting, or as apres-ski footwear. - Main material: EVA foam - Upper material: polyester fabric - ABS toe cap - Liner: polyester - Sole: rubber - Shock absorbing heel Note! Drying the boots is recommended to be done in room temperature. Using dedicated, relatively low temperature boot dryers such as the ones made by Therm-Ic is ok. Fubuki is Japanese and means a snow storm. Niseko
