Taking care of your feet is easy!
Blisters can quickly transform an awesome trip into a nightmare. Don't panic! Here's how to prevent and treat blisters in 4 easy steps:
1.Prevent blisters
Before leaving on a trip, it's essential to have the right footwear. It should be:
- The right size
- Wide enough for your feet
- Compatible with your orthotics if you have any
- Adapted to your total weight including your backpack
- Durable enough for the distances you plan to cover
- Rigid enough and with a sole compound made for the types of surfaces you'll encounter (sand, gravel, volcanic rock, granite, mud...)
- Made for the challenging terrains you might cross (wide trails, off-trail, flat, steep...)
- A good fit for the climate (hot or cold)
Did you know?
Fitting rigid hiking boots takes on average 1 hour in store. Start on the right foot and consult with expert boot fitters before leaving on a big trip. Your feet (and hiking partners) will thank you!
It's good practice to carry different types and thicknesses of socks on a big hike, especially with newer footwear.
- A light or full cushion merino wool sock is a good baseline
- A very thin synthetic liner sock will be a lifesaver if your feet swell or if it's really warm
- You can always layer a wool sock over a thin sock for more warmth or to prevent friction and blisters under the ball of the foot.
Wet and sandy socks are a sure way to get blisters. To prevent this, change socks during lunch break and take the time to remove and dry the insole if you can. Here's a pro tip: use a big safety pin and dry your wet socks on your pack while you hike
Lightweight gaiters are an absolute game-changer and will also protect from tick bites!
Efficient lacing
Even the best footwear in the world won't fit well if it's not laced properly. Here's 3 simple tips to help you:

Create 2 lacing zones
Use the lower hook or a couple of extra turns in your laces to create 2 lacing zones. For the lower zone, the aim is to have a firm fit in the middle of the foot with some space for the toes at the end.

Skip an eyelet
Give more space to your swollen toes or relieve pressure on top of the foot by skipping an eyelet.

Adapting the lacing to the terrain
You can adjust how tight the upper lacing zone is depending if you're going up or down. You want a tighter fit to protect the ankle on the downhills and a looser fit for more flexibility on the uphills.
2.Hot spots - the first signs of a blister
Act quickly to prevent blisters from forming in the first place
Blue skies, sunshine, rainbows...life is good on the trail! Until you start to feel a slight discomfort or rubbing in your footwear. Time to take a break! It might be a blister forming. Use the preceding tips to try and solve the problem: changing socks, removing sand or rocks, changing the lacing...

Common blisters and possible causes

Blister on the toes
Boots too tight in the front or swollen feet. Try changing for tinner socks or skipping an eyelet in the front.

Blister on the sole of the feet
Often during long descents because of poor lacing. Tighten the laces more, put on thicker socks or 2 pairs at the same time: thin and thick. This is also a good tip for heel blisters: the friction happens between the 2 pairs of socks and not on the skin.

Blisters on the heel
Common on long ascents with many possible causes, sometimes because the lacing is too loose, a stitch is rubbing (bad footwear design) or the heel is not positioned correctly in the heel pocket.. You can try tapping the heel strongly on the ground before lacing to correctly place it in the footwear. If nothing works, time to improvise! Sometimes, cutting the raised edge of the insole around the heel might solve the problem in a pinch. You can also shim it to raise the heel a bit.
3.The Blister first-aid kit

Benzoin tincture
Used as a taping base for bandage tapes and Opsites. It's safe, smells awesome and doesn't dissolve in water, so it's pretty hard to wash off clothing! Use it on the skin to get any type of tape or bandage to stick.

Opsite tape
Opsite tape is a very thin, flexible and breathable film that you can cut to size. Use it to prevent friction and blisters, protect the skin and on any type of lesion or abrasion. It's a first-aid super star!

KT Tape
KT Tape is a strong and flexible tape used in physiotherapy. It's durable, very sticky and dries quickly. Use it on hot spots to protect the skin (awesome for heel rub), but not on existing blisters.
4.Ouch!
Despite your best efforts, you now have a painful blister. What should you do? There's hundreds of ways to deal with blisters on the web, but here's Franc's personal strategy, our long distance hiking expert.
If your blister is intact and not leaking yet, use Benzoin tincture around it and KT tape or an Opsite to stop it from getting worse. This should get you through the day. If you caught it too late and your blister is pierced or very big, your goal will be to diminish it's size and promote healing once you get to camp.
Before bed, make an incision across the blister with a clean knife to drain the fluid and let it dry overnight, but keep the skin above it intact as much as possible. Before leaving in the morning, cover with a big piece of Opsite. It will be a bit painful during the day, but should hold until the evening and promote healing.
