I Always Get Blisters When I Hike – What Can I Do?

DSC_0142

No, really I always get blisters on multi-day hikes.  I’ve tried different shoes, socks, band-aids, tape, lubricants, on and on… I have managed to reduce the number of blisters, just can’t get away from the heel.  It must be a result of my days as a tap dancer.   Here are some suggestions to help you reduce the occurrence of your blisters using a common sense approach.

Let’s talk about what a blister is.  In the hiking realm, it is your skin reacting to heat and abrasion.  If the rubbing and heat continues along with some moisture, the damaged skin forms a small pocket of fluid under the first few layers of skin.  This fluid is your body reacting and trying to protect the skin underneath it.  Rarely do blisters form quickly.  Usually, you will start to get a hot spot.  Detected early enough, you may be able to prevent the mega-blister.

Thru-hikers have gotten blisters every where you can imagine, but most are on the heel, toes and balls of the feet.  As a hiker, if you put enough miles in and have prolonged periods of flat terrain or downhill – you will get a hot spot or blister.  Calluses are usually the result of a hotspot or blister in the same location.

Here are some tips to reduce the number of blisters:

– Pick your shoes wisely.  The heel should be snug, not loose.  Your feet will swell so you need a little extra room in the toe-box.  Don’t wear the new pair of boots on your week-long backcountry trip.  Break them in on some day hikes first.  If you have bunions, talk to a healthcare professional to see additional considerations when choosing shoes.

– Socks.  I wear a synthetic liner with good quality wool socks.  The liners wick away sweat and the wool socks provide some cushioning.  I’ve also used the synthetic socks with toes to cut down on the toe blisters with some success.

– Take a break after a few hours of hiking, remove your shoes, socks and air those feet out.  Bonus:  Stop near water and dip those puppies in there.  Awesome!    Use this opportunity to check for hot spots.  Keep some moleskin in your first aid kit and apply it to those spots.  It may prevent a full-fledged blister.

– When crossing streams, recommend you change out your non-waterproof boots for river shoes or sandals.  Hiking in wet socks and shoes is asking for trouble.

First aid for blisters:

– There are different types of blisters.  If you see blood, keep an eye and use some Neosporin to ward off infection.

– Don’t pop blisters unless they are too painful.   The fluid is protecting the skin underneath and may keep it from bleeding.  If you have to pop it, use a sterilized needle or safety-pin.  Hold the needle under a flame to sterilize.   You can actually run thread through the blister so the fluid drains out.  I have done this as a last resort and don’t recommend it unless you have the blister from Hades.  Again, use an antibiotic ointment.

No blog about blisters would be complete without real pics. I ran thread through this Godzilla size blister to help it drain. Yuck.

– In your first aid kit, keep moleskin, scissors, waterproof medical tape (duct tape will work) and even a needle and thread.  Use moleskin for smaller blisters.

– For your heels, you can apply duct tape to keep a hot spot from developing into a blister.  I wrap duct tape around my hiking poles; you can peel off what you need.    You can use a lubricant like Mueller Lube-Stickª for Runners Skin Barrier – 0.6 oz Stick – Each # 420206N . It helps to cut down on abrasion.

Oh, I really wasn’t a tap dancer, but I can hike like a billy-goat.  Do you have some tips for keeping the blisters away?  Please share them.DSC_0089


One of the Most Important Things About Hiking…

You ever heard of the adage “you can learn something new everyday”?  Well, maybe it’s not an adage, but it should be.  A couple of years ago, some young Marines taught me a valuable lesson on a backcountry hike.  The lesson was one that I’ve taken to heart.  Disclaimer: The observations that follow are based on my experiences and are not medical advice.

When you think about which part of your body takes the most abuse on the trail, what comes to mind?  For me it is the feet.  Your tootsies can really take a beating out there.  If you’ve been hiking for a while, you have probably suffered from some of the maladies that I’ll discuss. My first cardinal sin of hiking was buying shoes that fit.  In other words, I got boots the same size as my everyday shoes.  They worked great on short hikes on varied terrain.  However, my week of hiking in Yosemite demonstrated the flaw to my thinking.  After a long hike, the downhill stretch hurt my toes.  You see, the feet can swell and the arches tend to flatten a bit on long hikes.  The result can be a foot that is up to one size larger than normal.  Since the toes have nowhere to go, they bang up against the toe box in your boot.  The result may take a few days,  but the toenails turn black and blue and eventually fall off.  Lesson Learned – Buy hiking shoes/boots that are at least 1/2 to 1 size larger than normal.  You can make up the difference with thicker socks.

Blisters, unavoidable – right?  Not always.  While the primary cause of blisters is friction, moisture (sweat) is a key contributing factor.  Reduce the rubbing and moisture and you will typically get less blisters.  After your toes, the heels take the most abuse on your feet.  You can reduce heel rubbing by a shoe that fits well.  You can also use a lubricant made especially for runners which is somewhat effective.  Shoes that are too wide in the back allow for excessive movement and will rub those seven layers of skin off by lunchtime.  Some tips to reduce moisture – use synthetic sock liners followed by the appropriate thickness of wool socks.  The merino wool works well for me.  Together, these socks wick away moisture where it has a chance to evaporate.  Lastly, as far as blisters go, dirt in your shoe – it is an abrasive that increases the risk of blisters.  The solution is to pick up some gaiters to slip over your shoes.  There are many varieties from simple synthetic pullover to heavy-duty trail blazers that resist cactus.  They do a great job at keeping debris out of your shoes.

This downhill stretch was a 4,000 ft. elevation loss. The descents are harder on my feet.

By far, the most comforting thing that you can do on extended treks is to occasionally stop and take your shoes and socks off.  This is especially true on those warmer hikes, but the feet perspire on those winter hikes due to the thicker socks.  A 5 minute break cooling your jets will go a long way in warding of those blisters.  Massaging the bottom and ball of your feet  is very therapeutic.  Be careful, as I’ve read of hikers losing a boot over a cliff.  Can you imagine hiking out in your socks?

Sometimes the smallest rocks in your shoe feel ginormous.

On extended backcountry trips, it is imperative that you baby those feet at the end of the day.  I usually break out the wet or antiseptic wipes and give my feet a good cleaning.   It’s always a good idea to apply some triple antibiotic ointment to any open blisters or abrasions.  It is possible to get an infection from an open blister or raw area on your feet within days, especially if you fiord a few streams.   Afterwards, I’ll rub some  foot lotion or ointment (like Gold Bond or Kerasal)  to moisturize, before putting on a clean pair of socks at bedtime.  Your feet will appreciate it and the socks will keep your feet comfy.  Like many of you, I’ve logged hundreds of trail miles on these feet and they haven’t failed me yet.  Take care of them and you’ll be amazed where they can take you. 🙂
