Choose a comparable pair first
Darn Tough’s Hiker Micro Crew 1466 and Smartwool’s Classic Full Cushion Crew SW013000 differ in both cuff family and cushion terminology. A brand-versus-brand comparison should keep those distinctions visible rather than calling either one representative of every sock it makes.
Read the chart attached to the model
Use the correct men’s, women’s or unisex range for the selected construction. A medium in one brand is not a universal conversion. Darn Tough publishes average height differences between some men’s/unisex and women’s constructions.
Keep the cushioning language intact
Darn Tough separates yarn-weight labels from cushioning. Smartwool’s Classic pages distinguish full and extra cushioning with medium- and heavy-thickness language. Preserve those original terms instead of assigning a shared numeric comfort score.
Check the exact material variant
Current product pages supply the material blend for each model. Smartwool notes that content can vary by UPC, so compare the selected style and variant. Do not use a brand’s general merino reputation in place of the exact label.
Compare policies separately from lifespan
Darn Tough describes a lifetime replacement promise, while Smartwool describes a two-year satisfaction guarantee. Store returns may have shorter windows and conditions about use or washing. A longer policy is not a measured durability result.
