Furthermore, a hard gasket is incorporated inside the eyelet, creating a structure that can withstand the pulling force from the chain. This double reinforcement prevents tearing and greatly extends the product life. The chain spikes themselves are also resistant to harsh environments and are rust-resistant even in winter. 【Ergonomic Design Chain Spikes】These ice cleats have 25 spikes that firmly grip snow and ice, enabling stable walking. 16 spikes are widely arranged in the forefoot to support stepping, and 7 spikes are concentrated in the rearfoot to enhance heel stability. Furthermore, two spikes are added to the arch of the foot to further enhance stability during walking. Conventional designs did not have spikes in the arch of the foot, but this product adds spikes in appropriate positions based on ergonomics, realizing more natural and safe walking. 【201 Stainless Steel and High-Quality TPE Material】201 stainless steel, which is excellent in strength and resistant to rust, is used for the chain and spikes. The spikes are 2.2mm thick, combining durability and high grip. Furthermore, the rubber part uses high-quality TPE material for professional use that can withstand extreme cold, and can be used with confidence even in an environment of minus 55℃. 【Easy to Attach】Chain ice cleats can be smoothly attached like putting on socks, and can be used by both men and women due to the two sizes available. They are compatible with a wide range of shoe types, including mountaineering boots, sneakers, running shoes, boots, and trekking shoes. If you feel it is a little loose, you can secure it firmly with Velcro for safe support. 【In Various Scenes】Effective not only for mountaineering, but also on icy roads, muddy roads, slopes, and various other situations. It is an essential item for climbing Mount Fuji in seasons other than summer.
