Purchased in August 2021 and used 3 or 4 times in the mountains. The total walking distance is probably around 30-40km. I didn't use them much because they are not waterproof. They have been home-cleaned, but they are used items, so please purchase only if you understand that there may be some scratches, dirt, and scuffs. Below is the official description: These are lightweight shoes perfect for trail running and speed hiking. They use a mesh material with excellent breathability throughout. Synthetic leather and polyurethane sheets are used for partial reinforcement, achieving an optimal balance of flexibility and protection. Equipped with a lightweight and highly cushioned midsole and a sole with a unique pattern for excellent grip, they support light running. *They are not waterproof. Thank you for viewing. #TrailRunning #Montbell
