ASICS Half Tights Inner Muscle Spats, Size M Looks grayish in the light, but it's completely black. I used these for running, but I'm decluttering because I have too much running gear. I hope to pass these on to runners and triathletes. For size reference, I am 173cm tall and weigh 65kg, with an average build. I wore these a few times while running. □ Size: M (approximate) □ Condition: No tears or fraying in the fabric, but please check the images carefully. These have been handled by someone else, so please refrain from purchasing if you are overly sensitive. If you have any questions, please feel free to comment. Product Description: The ASICS "Inner Muscle Series" works the inner muscles through wear. By combining and arranging materials with different elasticity, it efficiently activates the inner muscles and improves posture balance. The Psoas Muscle Strengthening Spats [Hip Balance H Tights] feature an H-shaped high-elastic fabric in the hip area, the H-area structure efficiently loads the psoas muscle during exercise. Psoas muscle strengthening support is expected to improve performance, such as widening stride in running and stabilizing legs and hips in various ball games. It can also be expected to alleviate spinal misalignment and slouching in daily life.
