High-durability, industrial-grade traction aids (1 pair) suitable for walking on snow and ice. These are removable, anti-slip spikes that attach to your shoes. They can be used on icy roads, as well as for mountain climbing and leisure activities. They have excellent grip and are easy to attach, making them more compact than carrying snow boots. New L size 27.5～29cm 9.5～11US Please note that this is the shoe size, not the foot size, so please check the overall length of your shoes, such as sneakers with sturdy soles like Nike. Due to the strong elasticity, it can also cover 26.5cm (US8.5). Please be aware that the M size is for 25cm and up, so you may need to stretch it quite a bit to attach it. Various types are sold on Amazon US, but they are all expensive, so please consider this opportunity as winter approaches.
