Edge Blisters And The Two Patch Technique

What Is An Edge Blister?

An edge blister is a blister that’s kind of on the bottom of the foot, but it’s a bit on the side too. The location of these blisters makes them a little more difficult to prevent.

Applying Patches To Curved Areas - Like The Heel Cup

(I neglected to cover this in the video)

As highlighted by a customer recently, it's difficult to know how to apply patches to the very curved heel cup area of orthotics and some insoles.  And I agree, it can be tricky.

"I'm just now trying to fit the patches. I've watched all the videos but I'm having trouble due to the shape of my insoles. They are very scooped, which is probably why I'm getting edge blisters. Should I clip the edges so that there are no creases or should I apply two and overlap them? Any ideas?" 

There are too many wrinkles and creases. And there's only a small area of coverage right at the top of the heel cup, where protection is needed most for edge blisters.

As you slide your foot into the shoe, your sock is likely to catch on the top edge of the patch and drag it down

Can you see any problems with these patches? I can see three:

  1. There are too many creases

  2. The sock is going to catch on the edge of the patch at the top of the heel cup

  3. The area of coverage at the top of the heel cup (where we need the protection for edge blisters) is quite small

Here's How I Do It

No creases or wrinkles. And a wide area of coverage at the top of the heel cup.

we have to have creases somewhere and it's okay to have them at the back of the heel cup . Creases here are fine as your skin won't be irritated by them.

There Are A Few Reasons Why This Patch Will Work Better:

  1. There are no creases where your foot sits - so the patch is more likely to be comfortable

  2. There is a large area of coverage right at the top of the heel cup - so you'll be protected from edge blisters over a wider area

  3. There's no edge at the top of the heel cup for the sock to catch on as you slide your foot down into your shoe - so the patch will last a lot longer

Note: This is a small oval patch applied width-wise (widest from side to side) for maximum coverage. If you were still having trouble applying your patch, to make it even easier, you could turn your patch around and apply it length-wise (widest from top to bottom) but you would have a little less coverage this way. You can get both small and large oval ENGO Patches in the 6-Pack - below.
