How to Choose Socks

This article compares your choices.

Socks by Activity

Socks at REI are organized by intended activity. Each features subtle differences in construction:

Athletic/multisport socks: This broad category ranges from traditional white gym socks (updated with moisture-wicking fabrics) to technical socks intended for cross-training and running. Most provide some sole cushioning but have minimal bulk overall.

Running socks: These range from thin liner socks with very little padding to those with dense cushioning in the heel and ball of the foot. Some runners prefer less padding for a better fit in their shoes; others like more padding for added cushioning and reduced foot fatigue.

Walking socks: These offer cushioning and moisture-wicking properties for fitness walkers.

Casual socks: Though distinguished by their casual styling (colors, stripes, etc.), these lightweight socks, at least those found at REI, usually feature performance fabrics such as merino wool.

Lightweight hiking socks: These relatively thin socks provide a good fit for hikers with high-volume feet (i.e., feet that are wide or have a high instep). They wick away moisture and offer modest cushioning in the heel and ball of the foot. They are thinner, especially on the top, than midweight socks and can be worn with or without liner socks.

Midweight backpacking socks: Their additional thickness gives a good fit to hikers with low-volume feet (i.e., feet that are narrow or have a low instep). They offer more padding in the heel and ball of the foot than do lightweight hiking socks, plus cushioning on the top of the foot and leg for comfort on long trails. They can be worn with or without liner socks.

Mountaineering socks: These heavyweight socks are your thickest option, with extra bulk and padding for cold, rugged conditions.

Ski and snowboard socks: These are padded in the shin area and usually underfoot as well. Otherwise, they are thin and not intended to provide significant warmth; rather they are meant to protect your feet from pressure points and rubbing inside the boots. Their design also serves to not interfere with the energy needed to make quick turns.

Specialized Socks

Here are some multi-activity sock options to consider.

Liner socks: These are worn under a pair of regular hiking socks. Typically made of synthetics such as CoolMax^® polyester, they pull moisture away from the feet to the outer sock where it can evaporate. Liner socks are popular with hikers because they can be washed and dried more quickly than regular socks on long trips.

Toe socks: Like gloves for your feet, seamless "toe socks" help prevent between-toe blisters. (Note: Between-toe blisters can also be the result of too-tight shoes.) Typically made of synthetic fibers, toe socks are intended for running or hiking.

Fleece socks: These are a cozy choice with shoes or sandals, or by themselves as house slippers. The fabric wicks moisture but does not conform to the foot as much as a hiking sock.

Heated socks: These use low-amperage battery power to provide fast, shockproof heat. Popular for sedentary pursuits (e.g., fishing, spectator sports) in cold weather.

Sock Features

Padding: Look for padding on the heel and ball of the foot for cushioning and protection. Be sure the amount of padding does not make your shoe too tight. Padding is created either by increasing the density of the weave in those areas, or in some cases by weaving long-wearing materials like acrylic into those areas. This extra padding can be a real foot-saver on hard trips over rough terrain.

Arch reinforcements: Some socks offer a tighter, reinforced weave in the arch to improve support. This is primarily helpful if you have high arches, but can be useful for those with regular arches or flat feet as well. Without proper support, arches can develop arch pain or even plantar fasciitis, which can cause severe pain in your heels. Keep in mind, though, that your footwear is the key factor for arch support.

Height: In many cases, this is merely a personal or style preference. However, crew and quarter socks do offer abrasion protection from your boot tops, so we recommend socks at least this tall when you're wearing mid- or high-cut boots.

Fit: To get the right size, look for manufacturer-specific size information on any REI.com product page. When you try on socks, pay attention to how they fit in the toe and the heel. Correct length is the key criteria. If a sock is too long, it will bunch up over your toes. If it's too short, the sock will slide down into the shoe and feel tight. For heavily padded socks, try them on with your shoes to ensure they fit comfortably without making your shoes too tight.
