Choose a sock model, then use its size chart. This guide includes 4 Smartwool models, with their material, cushion and layer differences kept separate.

An ankle-height hiking sock with light cushioning along the bottom of the foot.

Keep in mind: An ankle cuff can sit below a boot collar. For higher boots, compare a crew that clears the collar.

The Mountain Range crew combines Smartwool’s light-cushion label with a 56% merino blend.

Keep in mind: Light cushioning is concentrated underfoot. Compare Classic Full Cushion if you want cushioning beyond that zone.

Smartwool describes this Classic Edition as medium thickness with full cushioning.

Keep in mind: Smartwool labels this medium thickness. Compare Extra Cushion only if you have room for its heavier construction.

The Extra Cushion Classic Edition uses the brand’s heavy-thickness construction.

Keep in mind: Extra cushioning adds more fabric inside the shoe. If toe room is already limited, compare Classic Full or a light-cushion model.
The lookup includes unisex chart. Match the chart to the exact model, then check the heel and toe fit in your footwear.
unisex: Use the range for the exact model. At a boundary, check heel position and toe room in your footwear; this chart does not supply a universal size-up rule.
Open the brand size lookup. See the fit checklist for heel position, toe room and cuff clearance.
The four Hike models in this guide allow gentle washing in warm or cool water and low tumble drying. 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.
