The opening boa uses an inner boa for heat retention effect from the circumference of the shaft to the forefoot. The Velcro tape makes it easy to put on and take off with you even when wearing gloves, making it easy to get dressed up on cold mornings.

The one-piece design provides a fully waterproof base that is approximately 9.1 oz (270 g) per shoe. When firmly held with Velcro, it prevents snow and water from entering the opening. The outsole has an uneven shape that gives you a secure grip on rough surfaces. These functional thermal boots are great for keeping your feet cool and working outdoors.

Staff Reminder: Usually 10.4 inches (26.5 cm), L size, slightly higher instep, and wide feet. I tried them on my socks.Although you can usually put it in a L size, these boots have just the right length of your foot, but the width of your feet was quite tight. If you try wearing the LL size, the foot length will be slightly over, but the width and front of the foot will not feel constricted, even if you wear a slightly thicker sock, you can put it in without issue. The uneven grooves on the outsole are deeply carved to provide a firm grip on rough surfaces.
