How to prevent blisters when hiking

There’s nothing worse than being a few hours into a multiday hike and feeling that slight irritation on your heel or toe. A blister’s coming through – and your hike is about to get less comfortable.

Read our tips on how to prevent blisters in the first place and what to do if you feel them breaking out.


Why do we get blisters?

To try and prevent blisters it’s important to know why we sometimes get them.

Blisters tend to form when moisture or heat affect your skin and it gets irritated or beat-up by friction or pressure. A few causes for this can be:

  • Tight areas in your hiking boots
  • Wrinkles in your socks
  • Sweat
  • Wet feet from river crossings or rain

Wear the right hiking socks

Socks can be underrated but they’re key components to preventing the development of blisters on your feet.

Wet fabric creates more friction than dry, so go for a pair of moisture wicking and quick drying socks. They’ll keep your skin dry to ensure it’s less sensitive to friction.

Wearing thick socks or two pairs at once isn’t the same as wearing quality socks that’ve been specifically designed for hiking. Quality hiking socks also have zonal padding to give your feet extra comfort.

Be sure to carry a spare pair of hiking socks in your pack – ones that you can change into should your current pair become damp and sweaty.

Choose synthetic socks or a merino blend over cotton ones (which absorb water quickly). We have a range of hiking socks to suit your mountain adventures.

Choose perfect fitting hiking boots

Perhaps the most important items you’ll take hiking are your hiking boots. Your feet cop a pounding from the variety of terrain on any given trail. Give them the support, comfort and protection they need to keep you moving freely.

It’s vital your feet are comfortable enough so they won’t slip or slide around the inside of your boots. There are essentially two problems that can come about with new shoes.

What to do if you do get a blister

There are a few ways to treat blisters, as they come in different shapes, sizes and places. In general you shouldn’t drain a blister, but rather leave the fluid to do its protective job for the new skin underneath preventing infection.

Really big blisters, or problematic ones (like under the toenails) are worthy of a doctors visit.

On the trail, a blister may be too big and painful to carry on. Carry a sterile needle in case you need to drain it. Make sure your first-aid kit includes disinfectant and bandages to minimise the chance of infection.

Boots that are too small

Give your feet enough wriggle room while taking into account swelling over the day. If you get scrunched toes, it can lead to bad blisters or blackened toenails.

Footwear that’s too big

It’s a smart idea to walk on an inclined ramp to test whether your heels stay in the same place on the uphill. Also check your toes don’t touch the front of your boots on the downhill.

Take your time to find hiking footwear that’s the ideal shape and fit for your feet – to help eliminate the risk of blisters.

Break your boots in

Rock your new boots around the house, yard and the block before you take them into the wilderness. Breaking in your footwear is vital for giving them time to soften and enable your skin to toughen – acting as natural padding against friction.

Just be sure to wear the socks you intend to hike in.

Tackle any hotspots straight away

When you feel a hotspot forming, stop to fix the cause and attend to the hotspot immediately. This is critical to preventing blisters on the spot – or at least minimising their effects.

Some fixes you could try when a hotspot flares up is:

  • Changing your socks – particularly if they’re damp or sweaty
  • Patching your hotspot – getting a blister-specific bandage like Compeed on it as soon as possible
  • Taping your hotspot – using a high quality tape that doesn’t move
  • Applying lubricant to the area – to minimise friction

Always carry a blister kit with you on any hike. When stopping for breaks, take your footwear off to allow your feet to breathe, cool down and dry off.

Treat blisters if you get them

There are a few do’s and don’ts when it comes to blisters. Take the following advice on board:

  • Don’t drain a small blister – it’s better to let the fluid do its protective job for your new skin underneath
  • Do apply a blister patch – and let your body treat the blister naturally
  • Do drain a large painful blister if it’s the only way to carry on hiking – by using a sterile needle to puncture the skin

Following these simple tips will go a long way to preventing blisters and increasing your hiking comfort on your next adventure.
