Soccer shin guards. These are mini shin guards. 【XS Size】 This is XS size, so please make sure you don't mistake it for S size. Please check the second image for a comparison between XS and S sizes (*^^*) Size is approximately 8cm x 5cm. These are mini-sized shin guards. My university student son has been using these in official matches since his high school days, and they work fine without any problems! He says that with these small shin guards, it's easier to play soccer and fatigue is significantly reduced. I haven't heard of them being unusable in official matches around me, but just in case, please be aware of the possibility. For those in a hurry, I will ship via Rakuraku Mercari (Nekopos) by the day after purchase!
