Keep in mind: Left and right shaping makes placement part of the fit. Check each side and compare a lighter sock if the medium cushion crowds your shoe.
The lookup includes men’s Hike Medium Crew chart. Match the chart to the exact model, then check the heel and toe fit in your footwear.
men’s Hike Medium Crew: Use the men’s chart shown on this exact product page. US women’s sizes are not published in that chart; a generic conversion is not used.
Open the brand size lookup. See the fit checklist for heel position, toe room and cuff clearance.
For men’s Hike Medium Crew IB0A578, machine wash cold on a gentle cycle and dry flat. Do not bleach, iron or dry clean.
A different instruction on the exact sock takes precedence over general brand guidance. Use the care lookup and your own drying estimate in the rotation planner.
The current US warranty covers faulty fabric, stitching or manufacturing for one year with authorized-seller proof of purchase. It is not a lifetime wear guarantee. The separate comfort guarantee is 30 days; retailer purchases begin with that retailer.
Direct online returns require an unworn, unwashed item in original packaging; final-sale and pro orders are excluded. The page says 30 days and uses both purchase and ship date wording, so begin within 30 days of purchase. Exchanges require a refund and new order.
