OESH - Warrior Zero-Drop Shoes | Size 6.5 | Zinc Gray with White Laces The healthiest all-day performance shoe on the market. Driven by Dr. Kerrigan’s Harvard research and fits all (wide, regular, and narrow widths), above a perfectly flat, patented unit Sole. Delivering consistent buoyancy and biomechanically synched to work with the body, fit soft and stretchy, hugging midfoot and heel like a comfy sock. Weigh just 7 ounces is light, especially important during vigorous exercise and all-day wear. Brilliant construction (elastomeric single-piece “unit” Sole and knitted, plant-based recyclable upper creating no production waste). Compared to a typical running shoe of 65 parts made in 360 assembly steps, these are 6 parts in 12 steps. No EVA foam, zero-drop (height difference between forefront and heel) so your foot lies flat just as it would barefoot. Machine washable. Condition: In EUC; worn ~3 times.
