Sock Geek Says:

Fine needle construction using soft, fine-grade Australian Merino Wool. Especially well-adapted for high exertion activity in a wide range of temperatures and conditions. The Wallaroo offers excellent supportive arch compression. Fine toe stitching. Structured cushioning at the footbed and dense cushioning at heel and toe where maximum impact occurs. Mesh ventilation channels deliver superior breathability, temperature regulation, and moisture control. Super comfortable for all day wear.
