As an active person, you’re likely familiar with how that burning sensation between your toes or the tender spot on your heel quickly transforms an enjoyable day into an uncomfortable ordeal. At Rocky Mountain Foot & Ankle, our Idaho foot doctors know exactly how frustrating blisters and other friction injuries are. More importantly, we’re also aware that what starts as a simple blister can develop into serious complications if not properly treated. The good news is that most blisters are entirely preventable with the right strategies and awareness.
What Causes Summer Blisters?
When friction creates heat between your skin and another surface—typically your shoe or sock—repeated rubbing causes the epidermis to separate from the other skin layers beneath it, creating a fluid-filled pocket. During summer activities, several factors increase your risk of developing painful friction injuries:
- Heat and moisture create the perfect storm for blister formation. When your feet sweat, your skin becomes softer and more susceptible to damage from constant rubbing.
- New shoes often contribute to blister development, too, especially when worn for extended periods without proper break-in time.
- Poor foot hygiene allows bacteria and fungi to thrive in the warm, moist environment inside your shoes.
Why Proper Footwear Selection Is Essential to Prevent Blisters
The right shoes are the foundation of effective blister prevention. They should provide adequate room for your feet to swell during activity, which naturally occurs with increased blood flow and heat. Here are some important considerations:
- Activity-specific footwear. Consider the specific demands of your planned activities when selecting shoes. Whether you’re a fan of hiking, an avid runner, a tennis enthusiast, or dedicated to some other type of sport, make sure to choose footwear that provides the right support and protection for your pursuits.
- Proper sizing. Shop for shoes later in the day when your feet are naturally swollen to their largest size. This ensures a more accurate fit for active use.
- Break-in period. Gradually wear new shoes over several short sessions rather than taking them directly on long adventures. This allows both your feet and the shoes to adjust to each other.
Sock Selection and Moisture Management Matter, Too
Another sure way to prevent blisters and other friction injuries is to match your socks to your activity. For example, synthetic materials such as polyester, nylon, and merino wool wick moisture away from your skin, keeping your feet drier during activity. Our Idaho foot doctors also suggest you look for:
- Double-layer design. Consider socks with an inner layer that moves with your foot and an outer layer that moves with your shoe, reducing friction between your skin and the sock material.
- Seamless construction. Look for socks with flat-seam construction to prevent ridges and bumps that can create pressure points.
- Moisture control. Apply foot powder or antiperspirant to your feet before putting on socks to further reduce moisture and create a protective barrier.
When Blister Prevention Isn't Enough
Despite your best efforts, friction injuries might still happen. Recognizing the early signs allows for prompt treatment that can prevent worsening. First, clean any open blisters thoroughly with soap and water, then apply antibiotic ointment and a sterile bandage.
- For small, intact blisters, protect the area with specialized bandages or moleskin padding. These products cushion the area and prevent further friction while allowing natural healing. Avoid popping small blisters, as this increases infection risk.
- Larger blisters that interfere with walking may require drainage by one of the professionals in our Caldwell or Meridian offices.
The Hidden Dangers of Repeated Friction Injuries
While a single blister might seem minor, repeated friction injuries could lead to more foot problems. For example, chronic pressure and rubbing often result in permanent skin changes, including thickening and scarring that make future blisters more likely.
Open blisters provide an entry point for bacteria and fungi, potentially leading to cellulitis or other serious infections—individuals with diabetes or circulation problems face particularly high risks from these complications. Additionally, repeatedly traumatized areas may develop chronic pain or sensitivity that persists long after the original injury heals.
