Brand new! These are US Mens Size 11 but run a little small and fit more like a 10.5. Super cozy, comfy and perfect for daily life in cold climates or outdoor hiking on a trip to wintery place.

The specially designed barefoot inner design with a large toe box not only gives your foot the necessary space and perfectly adapts to the shape of your foot but also bids farewell to sore feet, ensuring your winter walks are pure comfort and joy.
