Performance Running Shorts designed in Colorado by Marathon Runner Michael Culley. The Endurance by INHERENT performance running shorts are specifically designed for distance runners. These shorts, created by Michael Culley - a marathoner, ultra marathoner, and 10x Boston qualifier - prioritize comfort and durability. The sturdy waistband, featuring a drawstring and spandex liner, keeps the shorts securely in place, preventing them from falling down or riding up during your long runs. The shorts also come equipped with 8 pockets, including 2 liner pockets for your phone or other items, front and back zipper pockets for secure storage, and 2 mesh pockets on each side for water bottles and nutrition. Additionally, elastic loops on each side are provided for gels, and a heavy-duty elastic band on the back to hold a top layer that you may remove during your run. Available with a 7" inseam, and soon to be released with a 5" inseam, these shorts are perfect for your long, unsupported runs and for races where you bring your own nutrition.
