Ccompression sleeves, in particular, have seen widespread use in recent years. Although the sleeves have been prescribed by physicians for years because of their recognizable benefit, athletes have come to really embrace their usefulness more recently for a variety of reasons. Many long-distance runners, in particular, have really come to rely on them and incorporate them as an indispensable part of their workout gear. Among the main reasons they’re so positively-received is the way compression sleeves protect limbs from injuries to a certain degree, as well as provide a good deal of support particularly in the joint areas.
