NAILEKESI | Long Knee Support Knee Guard for Men Warmth Protection for Old Cold Legs

I'm 70kg and 175cm tall. Before ordering, I asked the shop for advice, saying my weight was close to 70kg. They suggested I choose XL. After receiving the goods, it was very loose, unlike sports gear that has that tight and snug feeling. I worked with the shop, who had a good attitude, and agreed to exchange it for an L size. I tried it on right away yesterday, but the calf part was still loose. I pulled it up to the thigh, and then the calves felt wrapped, but it felt more like tights, lacking the needed tension. Surprisingly, when I went downstairs and barely reached the basketball court, the upper part of the thigh slipped down to the knees, bunching up again. Pulling it up didn't help as it kept sliding down, overall the usage wasn't comfortable for two reasons: too loose and a bit too long.

The ankle opening is a bit loose; maybe it could be knit a bit smaller at the bottom.
