Best-possible weather protection and ankle support for every outdoor activity and every level. The Tomir Waterproof helps you conquer all-day technical hikes through deep snow and week-long adventures through intense rain. Along with superb ankle support, all-foot comfort, and highest-possible waterproof protection, the boots also tread light, using as little material as possible, with a climate-neutral waterproof membrane. Technologies include: Sympatex® waterproof membrane (100% waterproof, 100% windproof, optimized breathability and durability; PES membrane is 100% climate neutral, 100% recyclable, PFC-free, and bluesign® certified). VIBRAM® Megagrip ensures a secure lock on wet granite or steep gravelly trails and is long-wearing. VIBRAM® Litebase outsole is thinner (by up to 50%) and lighter (by up to 30%) for energy saving, with 5mm lugs and an 8mm drop. Durable ripstop upper made of polyester water repellent ripstop mesh protects the Sympatex® waterproof membrane. Asymmetrical lacing increases support and reduces pressure points. EVA midsole offers lighter weight, supreme cushioning, and step-enhancing rebound (with a 31/23mm stack height). Commitment & Origins: Made in China by Fulgent. Sole: 100% rubber. Upper: 50% TPE | 22% polyester | 28% monofilament nylon.
