Functional Fit socks, size L. Purchased from Step Sports. I am selling these because I am using socks from another brand. I've used them about 20 times, but the fabric is durable and shows no signs of wear, so they can still be used. If purchased individually, they are available for 800 yen. I will respond via message. #running #jogging #socks #functionalfit #Tabio #marathon #stepsports
