Cushion and weight labels describe this brand’s construction. They do not establish a shared thickness or temperature rating.
Check the size and the shoe together
Start with the men’s / unisex chart for this exact model. Use the brand size lookup to find the published range, then check the heel position, toe room and cuff in your footwear.
The maker does not give a heel-to-cuff measurement. Try the socks with your boots to see whether the cuff sits above the collar. See how sock heights differ.
Try the selected size with the shoes and insoles you plan to use. Added cushioning should not crowd the toes or distort the heel position. The footwear-fit checklist explains what to check.
Care for the exact pair
For men’s Hike Medium Crew IB0A578, machine wash cold on a gentle cycle and dry flat. Do not bleach, iron or dry clean.
Use the care lookup for this model’s wash and dry directions. A general wool routine should not override instructions for a membrane, a two-layer construction or a specific treatment.
Another sock to compare
Both constructions contain animal fiber (wool or alpaca). This changes from anatomical to conventional. Check that the changed construction suits your footwear.
Darn Tough Men's Hiker Micro Crew Midweight Cushion uses its own size chart. Compare the two socks to see where their height, material, cushioning and care differ. Similar fields do not establish an identical feel in your footwear.
