Ships in 1-2 business days | Based in Flagstaff, AZ | Est. 1999 Designed for ultralight, aggressive traction Kahtoola's MICROspikes® Ghost takes ultralight footwear traction to the next level. Move fast and travel light with high-performance MICROspikes® grip designed for snowy, mountainous terrain. Weighing 43% less than the original MICROspikes® footwear traction, the MICROspikes® Ghost cuts bulk without compromising strength by replacing steel chains with an abrasion-resistant TPU matrix. Kahtoola's weight-saving, durable design makes it the perfect traction device for ultralight thru-hikers needing traction on technical terrain. Twelve heat-treated stainless steel spikes provide aggressive grip, while hybrid elastomer harness sheds ounces and balances stretch and structure for a secure fit. Packs small, and performs big for dependable traction and long-lasting durability wherever the trail leads. Features: Twelve hardened stainless steel spikes per foot - Heat-treated, corrosion-resistant spikes dig into icy terrain for a confident grip Abrasion-resistant TPU matrix - Ultra-tough polymeric base replaces steel chains underfoot to reduce weight without sacrificing durability Hybrid elastomer harness - Features stiffer TPR at the top of the toe for security and stretchy TPE at the heel for a snug, lightweight fit Articulating rivets - Allow spikes to move independently to improve grip on uneven terrain and minimize snow buildup Patented reinforced eyelets - TPR inserts embedded at the harness connection points strengthen key stress areas for long-term reliability Includes: Pair of MICROspikes® Ghost Ripstop nylon tote sack _______________________________________ Specs Packed size: 4.5" x 4" x 2" | 11.5cm x 10cm x 5cm Spikes: Length: 0.36" | 9mm 12 spikes per foot Sizing Guide: Size US Women's US Men's EU X-Small 5 - 7 - 36 - 38 Small 7 - 9 6 - 8 38 - 40 Medium 9 - 11 8 - 10 40 - 43 Large 11.5+ 10 - 12 43 - 45 X-Large - 12 - 14 45 - 48 *sizes are approximate and are for trail runners and hiking shoes Weight (pair): XS: 6.4oz | 179g Small: 6.5oz | 184g Medium: 6.8oz | 192g Large: 7.1oz | 200g XL: 7.4oz | 208g Materials: Spikes: Heat-treated, corrosion-resistant 400-series stainless steel Traction Matrix: Thermoplastic polyurethane (TPU) Harness: Thermoplastic elastomer (TPE) and thermoplastic rubber (TPR) Reinforced eyelets: TPR ________________________________________________________________ Care Instructions: Wash with lukewarm water and air-dry (do NOT dry with heat).
