Best Running Socks to Prevent Blisters

Why Blisters Happen When You Run

There a few reasons you are getting blisters when you run:

• Friction

  • Foot rubbing against the shoe causing stress on the skin. This triggers an immune response to prevent any further damage to deeper layers of skin.

• Moisture buildup

  • When your skin is exposed to too much moisture for an extended period of time it absorbs the water becoming soft, white, and wrinkly, making it easier for the skin to separate which, alongside the damage from rubbing, causes blisters.

• Poor shoe fit

  • Whether too big or too small, the wrong size causes more friction. When wearing shoes that are too big, your foot will slide around in the shoe causing increased friction. When wearing shoes that are too small, your feet are more exposed to hot spots, which result from material pressing too tightly against the foot. 

• Cotton fabric

  • Cotton Fabric traps moisture in better than any other fabric which leads to more friction as well as moisture build up.

What to Look for in Anti-Blister Running Socks

• Moisture-wicking materials (synthetic or merino blends)

  • Keep the feet cool and dry using capillary action to draw the moisture outward and away from the foot.

• Seamless toe construction

  • Manufacturing the sock in a way to get rid of the large, uncomfortable seam that runs across the toe to reduce rubbing in that area of the foot.

• Targeted cushioning
  

  • Targeted cushioning on hot spots drastically reduces rubbing and provides a more comfortable feel, keeping the skin structurally intact.

• Snug, anatomical fit

  • This ensures that your socks and shoes move with you as opposed to allowing your foot and sock to slide around causing hot spots and friction.

• Arch compression support
  

  • The targeted arch compression allows for an even more snug feel on your sock reducing bunching or sliding, providing a pain free experience for those who suffer from plantar fasciitis as well.

Thin vs Cushioned Socks for Blister Prevention

Both options help in different situations and in different ways and here is how:

• Thinner socks allow for less friction when wearing tighter shoes.
  
  

• Cushioned socks are better for long runs as they absorb shock and eliminate distraction.
  
  

• The way your socks fit matter a lot more than the thickness. Keeping a snug fit to eliminate bunching and sliding is much more important.
  
  

How to Prevent Blisters on Long Runs

Here is some non-medical, but practical advice for avoiding blisters:

• Wear moisture-wicking socks

  • When there is too much moisture on your feet it makes your skin softer and more susceptible to rubbing and separating. This ultimately causes blisters.

• Trim toenails

  • Keeping your nails tidy prevents them from slamming into the front of whatever shoes you are wearing decreasing rubbing and likelihood of blood blisters under the toe nails.

• Break in shoes gradually

  • Slowly allowing shoes to mold more to the shape of your foot reduces stress on your foot without forcing your foot to fit into a shoe on a long run. Gradually allowing your foot and your shoe to form a relationship will drastically reduce blisters.
    
    

• Rotate shoes

  • Putting your foot in a different environment keeps from hotspots forming in the same spots on your foot. Hot spots are ground zero for blisters on your foot.
