Most people will sweat one cup of water a day through their feet, which makes a good pair of socks vital for on-trail comfort.

Moisture management
Dry feet are less likely to blister or overheat, and a good sock will complement a boot’s lining by creating a gap which allows moisture to be drawn away from your foot, through the boot lining, to be released into the air.

Seams
Chafe-free seams lay flat against the skin to reduce pressure points. 

Materials
All socks have different blends of synthetic and natural fibres. The exact mix will determine the quality, durability and comfort of the sock. Here’s what the various fibres do:

Wool: insulates the foot and helps control moisture. Merino is naturally anti-bacterial and odour-resistant

Lycra, spandex, elastane: keep socks up

Nylon: adds durability

Synthetic materials like Endurofil or CoolMax: wick moisture

Construction
Socks should fit snugly and stay put when they’re on. An elasticised arch and ankle prevents the sock sliding forward and bunching around the toes. The weave – in various thicknesses and knits – creates airspace against your skin to help keep feet dry and move moisture into the boot lining. 

Comfort
Padding is provided in key areas to absorb pressure from your boots. Areas that are frequently padded are the heel, arch, toes and the shin.

Ventilation
Ventilation panels enhance comfort by helping feet remain cool and more efficiently wick moisture.

Fit
Try different pairs to make sure the fit is spot on – excess material can lead to rubbing which could cause blisters. If you’re unsure, the length of your forearm from inside elbow to wrist should be the same length as your foot. Lay a sock along your arm to determine the size you need.
