World Rugby Law 4.1 says clothing must comply with Regulation 12, and Law 4.2 lists socks as standard clothing. Rugby socks can have ribbed support, flat toe seams or dense heel, toe and underfoot padding; grip styles add internal and external silicone dots in one maker's model. Compare exact construction and fit with your boots, since listed features alone do not establish a performance benefit.
World Rugby Law 4 requires socks as part of the standard match kit. The purchase choice is between designs and construction details: traditional playing socks, models with extra padding, and socks with silicone grip dots. Compare the exact product rather than assuming every rugby sock has the same fit or features.

These are examples from different models and regions, not a ranking or a universal product standard. Manufacturers describe their own construction; those descriptions do not prove how a sock performs in play.
Check match clothing and fit
Law 4 says all clothing must comply with Regulation 12 and lists socks as standard clothing. Read the current World Rugby permitted-clothing law and check any additional competition kit requirements.
Use the size chart for the exact sock, then check it with the boots and kit you plan to wear. If a padded or grip design changes the way the boot fits, compare another size or construction. For jersey cut and sleeve rules, see the rugby jersey fit guide; for other apparel charts, use the women’s rugby kit fit guide. Cold-weather clothing rules are covered in the rugby base-layer guide.
