Simple and stylish black side-gore boots. - Brand: North Date - Color: Black - Style: Side-gore boots - Established: 1941 Thank you for viewing. This is an insole from the Hokkaido-based brand "North Date." They research icy and snowy road surfaces, and their products are characterized by anti-slip processing such as W-grip spikes. The entire insole uses a warm and soft fleece material, and heat-retaining insulation is also used. Antibacterial treatment is also applied. I wore them once, but they didn't fit, so I've been storing them at home.
