La Sportiva winter mountaineering boots. Used for winter mountain climbing about 4 times. I am selling them because I no longer have the opportunity to climb snowy mountains. Please check the details in the images. These boots are suitable for winter use up to 2000m peaks and for late-season snow climbing up to 3000m peaks. They have PrimaLoft insulation and are very warm. They have front and rear welts, making them compatible with various crampons. Thank you for your consideration. - Brand: La Sportiva - Color: Yellow/Black - Design: Mountaineering boots for high altitudes - Features: Waterproof, durable materials - Sole: Grippy rubber sole - Size: Unknown (not visible in the images) Thank you for looking.
