Altra Olympus 6 Women's, size 24.5 US7.5. I've tried them on a trail for about 20km, but I'm selling them because I don't have a chance to use them. Used, no box, so no returns or exchanges. 【Product Description】 The Olympus is loved by many for long-distance trail running over 100km and mountaineering with heavy loads. One reason for this is the MAX cushioning with a 33mm stack height. This effectively cushions the impact from the ground. The Olympus is classified as a "thick-soled shoe," but its outstanding stability attracts many people. This stability is achieved by placing guide rails on the inside, a function that supports the foot when it tends to collapse inward, and a design where the sole flares out towards the ground, increasing the contact area. Furthermore, the Vibram Megagrip sole provides excellent grip, which is a major factor in its support among mountaineers. Another feature is the wide toe box. It maintains comfort even if your feet swell, preventing the unpleasant feeling of wanting to take off your shoes. The zero-drop shape makes it easier to land with your entire foot, especially when receiving strong impacts on downhill slopes, maximizing the foot's natural shock absorption ability. In addition to the reasons why the OLYMPUS series is supported, the following points have been updated in this Olympus 6: ・Increased mesh area to improve breathability and dry faster. ・Changed the lug pattern to further enhance traction and stability. ・Added a premium Achilles pillow to the heel for improved fit and feel. ・Changed the toe guard to a material that is neither too hard nor too soft. This makes it less likely to hurt your toes when they hit the tip of the shoe on downhill slopes. ・Changed the tongue to a thicker one. This makes it less likely to hurt the instep even after long hours of use. ・Weight: 289 g (Womens US8.5 / 25.5cm) ・Midsole: Compression-molded EVA foam ・Outsole: Vibram® Megagrip ・Stack Height: 33mm ・Upper: Engineered mesh
