These safety and cold-weather work boots were purchased a year ago but never used. There appears to be some staining on the surface, but when I asked the shoe store where I bought them, they said, "It's because of the high natural rubber content," so I think there's no problem. Spring is just around the corner, but outdoor and mountain work will still be cold. These are work boots that keep your feet warm, are safe even if something falls on your toes, and meet JIS standards. The rubber on the surface is designed for work in cold regions. The lining has a multi-layered structure with a quilted liner with batting, making it ideal for work in cold regions. (Antibacterial) They come with a cover to prevent rain, snow, and mud from entering, and are thick and highly insulated. Felt is sewn into the soles to reduce coldness from the ground. They come with cushioned cup insoles to reduce fatigue during work. These are safety work boots with steel toe caps. (ISO-approved quality) The soles have shock-absorbing material in the heels. The soles are non-slip with good grip even in cold regions. 【Safety Cold-Weather Work Boots】Safety Bear #1001 Color: Navy Size: 26.0cm Accessories: Adjustment spacer 《Features》 ・Improved heat retention by adopting the new quilting "BLAXX" ・Adoption of soles with shock energy absorption in the heel ・40% improvement in slip resistance compared to conventional products ・Antibacterial and deodorizing cup insoles keep the inside of the shoes comfortable ・Hood prevents snow, soil, and mud from entering 《Uses》 Manufacturing, construction, transportation, warehousing, fisheries, forestry 《Specifications》 Standards: JIS T 8101 S Approved Weight: Approximately 1,860g (both feet) Height: 43cm (from the sole to the top of the hood) Hood height: 15cm Opening circumference: 40.0cm Foot circumference: 25.5cm
