Trino® Sprinters - Cushioned - Onyx - New Edition

These crew-height athletic socks combine eucalyptus tree fiber with merino wool to create a fabric that resists odor naturally and pulls moisture away from skin. The mesh knit breathes where heat builds up, while reinforced panels at the heel and toe handle the friction points that usually wear through first.

The cushioning sits underfoot without adding bulk through the ankle or cuff, so they work inside running shoes or everyday sneakers without crowding. The natural fibers do the work that synthetic treatments try to replicate—wool regulates temperature whether you're warming up or cooling down, and eucalyptus fiber stays light even when you're sweating.

Crew length keeps them visible above low-top shoes and prevents that slipping-down feeling mid-run. The fit accommodates a range of sizes within each option, from women's 5 through men's 14, with the mesh adapting to different foot shapes without pinching or sagging.

Because both materials come from renewable sources, these socks skip the petroleum-based synthetics common in athletic wear. Merino is naturally finer than regular wool, so there's no itch against skin, and eucalyptus fiber adds a smooth, cool feel that works for long wear. Durability comes from the reinforced construction rather than chemical coatings, so they hold up through repeated washing without losing their shape or odor resistance.
