AREth Snowboard Boots - 25.5cm, No Box These boots feature Vibram's Arctic Trek sole, which resists hardening even in cold climates and provides excellent grip, making them ideal for walking on snow. A breathable waterproof film is used inside the upper, designed to prevent water from penetrating to the interior even if the fabric surface gets wet. The upper's inner padding uses Thinsulate, a material that traps heat while allowing moisture to escape. The insole utilizes POLIYOU®, a recycled material that combines cushioning and odor resistance. The foot width (width) of this model is E~EE, the same as other models. However, the insole is thicker than other models, at 7mm, so it may feel a bit narrower. (Other models have a thickness of 3mm) Quoted from the Rave website. I usually wear 24.5cm sneakers, and based on the description, I purchased the 25.5cm size. However, they felt a bit small for my feet, so I am selling them. These are new, unused boots, only tried on. Thank you for viewing.
