Rydgo Trainer Liner Socks

The Rydgo Trainer Liner Socks provide the minimal-profile, low-cut sock solution for the full range of low-top trainer styles — providing effective moisture management and blister prevention in the most discreet possible sock construction that remains fully functional as a protective barrier between the foot and the shoe interior. The liner is constructed with a heel cup that rises to 15mm above the shoe collar line, providing the minimum coverage necessary to prevent heel blistering from shoe backstay friction while remaining below the visible line of all low-top trainer styles when the foot is in motion. The heel retention system uses a continuous perimeter silicone bead positioned at the mid-heel that provides 360-degree grip against the shoe interior on all sides simultaneously, preventing the front-to-back and side-to-side movement that causes liner socks to slip down and bunch during walking and running. The footbed uses a 60% polyester / 35% nylon / 5% elastane moisture-wicking construction that draws sweat from the foot surface rapidly — the critical performance requirement for a liner in a shoe where airflow and moisture evaporation are both limited by the shoe’s enclosed construction. The toe profile is cut to sit below the toe box stitching of standard trainer styles, maintaining the invisible appearance regardless of shoe style variations. Light cushioning pads at the ball-of-foot and heel provide minimal protection from pressure concentration without adding visible bulk. Available in XS through XL in Black, White, Nude, and Grey. Sold in packs of six pairs. Machine washable to 40 degrees. The Rydgo Trainer Liner Socks are the invisible essential of the everyday trainer wardrobe.
