Crew socks are usually made of wear-resistant and stretch resistant materials, which can reduce direct contact between skin and external objects to a certain extent, thereby reducing the risk of abrasion.
However, it should be noted that crew socks cannot completely eliminate the risk of scratches. In some extreme situations, such as high-intensity exercise, falls, etc., abrasions may still occur. Therefore, when carrying out high-risk activities, in addition to wearing crew socks, other protective measures should also be taken, such as wearing appropriate shoes, using protective gear, etc., to minimize the risk of scratches.
In short, wearing crew socks can to some extent reduce the risk of ankle and calf abrasions, but it does not completely guarantee the avoidance of abrasions.
