Neither hiking insoles nor thicker socks are universally better for foot comfort. Thicker socks add cushioning and warmth but use up space inside a boot; an insole changes the footbed’s support and the shoe’s internal volume. Choose based on the problem you are trying to solve—and keep the footwear comfortable after the change.
What changes when you add a thicker sock or an insole?
Socks and insoles do different jobs. A thicker hiking sock changes cushioning, warmth, moisture handling and how much room your foot occupies in the boot. An insole changes the feel and support of the footbed, and can also change how much internal space is available. For background, see REI’s guides to hiking socks and insoles.
Which option fits your comfort problem?
| Your need or problem | Thicker hiking socks | Aftermarket insole |
|---|---|---|
| More cushioning underfoot | Adds cushioning at the heel and ball of the foot, but may make the footwear too tight. | Changes the footbed feel. A supportive model may feel comfortable through stability rather than softness. |
| More warmth | Can add warmth in cold conditions; heavy socks may be too warm in mild or hot weather. | Warmth is not the main role established by the cited guidance. |
| A low-volume foot or roomy boot | A midweight sock may provide a closer fit for some low-volume feet. | A suitably selected insole may take up excess space, including around the heel. |
| More support or less heel slip | Does not replace footbed support. | Some supportive insoles may help stabilize the heel or suit selected arch-support needs. |
| Tight or pinching footwear | May make tightness worse. | May also crowd the shoe. Check for pressure and whether the insert takes up too much volume. |
| Moisture or blister concerns | Choose a well-fitting hiking sock in a suitable fabric. REI advises against slow-drying cotton for active hiking. | An insole alone is not established as a blister-prevention solution; fit and friction matter. |
These are functional differences, not results from a head-to-head clinical trial. The cited footwear guidance does not establish that either option produces better comfort outcomes for all hikers.
How thick should hiking socks be?
Match sock thickness to the fit of your footwear and the conditions on the trail. REI’s sock guide describes midweight backpacking socks as more padded than lightweight socks and potentially suitable for low-volume feet. Heavier cushioning may suit colder weather or rougher trips, but can feel bulky or too warm in other conditions.

Try the socks in the hiking footwear you intend to wear. A sock that feels comfortable on its own is not a good choice if it makes your toes crowded or creates pressure in the boot. For mid- or high-cut footwear, consider sock height as well as thickness: the sock should cover the skin that could rub against the boot top.
When should you try an insole?
Consider an aftermarket insole when the concern is footbed support, heel slippage or excess room—not simply because a softer-feeling product sounds more comfortable. An insole’s shape and volume affect how your foot sits in the shoe. REI’s insole guide recommends removing the stock insole before assessing a replacement.
Rank #2
- Hiking Insoles for Men and Women: The arch is medium and cushioned, not stiff. They are soft enough for comfort over ten miles, but firm enough to keep your foot steady on rocks and roots. You will really notice the difference on long downhills
- Up to 56% Shock Absorption: When you carry a full pack, every step can feel heavier. Our shock layer takes in up to 56% of impact before it reaches your knees and lower back, so you stay comfortable all day
- Up to 47% Energy Return: The arch returns up to 47% of the energy you put into each step, rather than just absorbing it. It also helps take pressure off your knees when you walk downhill. By the end of a long day, your legs will feel the difference
- Dry Feet on Tough Climbs: A breathable cover and non-sweat layer pull heat and moisture away from your skin, keeping your boots drier on steep climbs and in warm weather. Wet feet cause blisters, and this helps prevent them
- Sized for Men and Women who Hike: Use the size chart to find your fit. Place your boots' insoles on top and trim around the front for an exact fit. These insoles are light enough for trail runners and tough enough for backpacking boots
- Take out the footwear’s stock insole.
- Place the replacement in the shoe and check how your foot sits in it.
- Assess stability, pressure and the fit around the heel cup.
- Check whether the replacement leaves too much or too little room. Do not keep it if it creates pinching or crowds your toes.
Will thicker socks make your boots too tight?
They can. A thicker sock takes up more of the room inside the boot, so a boot that fits well with a lightweight sock may feel tight with a heavier one. An insole can also reduce available space. REI’s guidance is that sock thickness depends on footwear fit; its hiking footwear guide recommends evaluating fit with the socks you plan to wear.
If a change causes persistent pressure, pinching, numb-feeling tightness, heel instability or toe crowding, stop using thickness as a fix and reassess the footwear’s fit or model.

Do socks or insoles prevent blisters?
Neither is a guaranteed blister cure. Blisters are associated with friction, pinching or feet jamming against footwear. A suitable sock and properly fitting footwear can help address contributing conditions, but adding a thicker sock or an insole does not by itself establish that blisters will be prevented. If you feel a hot spot while hiking, address the friction early instead of continuing until it becomes a blister. REI explains these factors in its guide to preventing common hiking injuries.

- Need support or want to address heel slip or excess footbed space? Test a supportive insole after removing the stock one, and check the resulting fit.
- Feel rubbing at the boot top? Check sock height as well as thickness.
- Does either change create pressure or crowding? Reassess the footwear instead of forcing the change.
