These men's organic cotton active crew socks in a bold, clear scarlet red are a refined take on the classic crew tennis sock, reworked for more support and a cleaner look. Organic cotton with a touch of stretch gives an athletic fit, and the classic crew length works for everything from casual outings to smarter settings. Small details like a good pair of socks make a noticeable difference to how an outfit feels through the day.

Key Features

• Blend of 70% organic cotton, 28% polyamide and 2% elastane
• A refined take on the classic crew tennis sock
• Extra brushed inner sole for cushioned, soft comfort underfoot
• Medium-high rib for a clean, tidy look
• Reinforced heel and toe that resist everyday wear
• Athletic fit with added stretch for support

Fabric & Care

Made from 70% organic cotton, 28% polyamide and 2% elastane. We recommend machine washing at a cool temperature with similar colours and air drying. Check the care label for full instructions. Turning socks inside out before washing helps protect the knit surface.

Fit & Sizing

Classic crew cut with an athletic, supportive fit. Available in EU sizes 36-40 and 41-46. If you are usually at the top of a size range, comparing with a pair you already own helps you choose.

How to Wear It

Wear the scarlet red pair with navy, white and charcoal outfits. They look right with white trainers (sneakers) and shorts on court days, and just as considered under chinos with suede shoes. Buy a few colours to rotate through the week and keep your sock drawer simple and coordinated.

Compare your measurements with the size guide beside the size options.
