Are they elastic, or is there velcro??? their just like compression sleeves but, shorter right???

nike guard stays are velcro i believe. i got two pairs of guard holders from ebay which are elastic which are meant to be put below the shinguards. they work pretty well too.

they are elasticated with velcro fastening. meant to be half on leg half on shinpad they work amazin for me but then my legs arent exactly the biggest
