About this product

The Mammut Taiss Light Mid GTX is a women's single mountaineering boot built around a balance of low weight and reliable performance on alpine terrain. Weighing 15.2 oz per boot in a size 7.5, it uses Mammut's Georganic 3D Technology to shape the microfiber, schoeller Soft Shell, textile ripstop, and mesh upper closely to the foot, promoting a natural fit during extended approaches and summit pushes. The schoeller Soft Shell contributes both protection and comfort, while a fully seam-sealed GORE-TEX Performance Comfort membrane keeps moisture out across snowfields and wet trails. Underfoot, a Vibram Ascension Litebase sole delivers dependable traction on mixed wet and dry surfaces without unnecessary weight, and the PU midsole provides cushioning support. A two-zone lacing system lets the wearer fine-tune fit independently across the forefoot and ankle. The boot is compatible with strap-on crampons, making it suitable for glacier crossings and icy traverses. Mammut backs the boot with a lifetime manufacturer warranty. Note that this product contains PFAS chemicals.

What people are saying

Reviewers consistently praise the Mammut Taiss Light Mid GTX Women's for its exceptional lightweight design, calling it one of the lightest crampon-compatible mountaineering boots available. The Gore-Tex waterproofing and Vibram Litebase outsole earn strong marks for keeping feet dry and delivering reliable grip on varied terrain. Ankle support, durability, and overall comfort over long days are also frequently highlighted. The most common complaints center on the narrow, asymmetric toebox, which does not suit all foot shapes, and the lack of insulation, making the boot less ideal for very cold conditions. Some reviewers also note a spartan feel underfoot due to minimal cushioning.
