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?"
Can you see any problems with these patches? I can see three:
There are too many creases
The sock is going to catch on the edge of the patch at the top of the heel cup
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
There are a few reasons why this patch will work better:
There are no creases where your foot sits - so the patch is more likely to be comfortable
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
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.
These oval-shaped ENGO Patches provide versatility for any blister situation. The shape makes them easy to apply to any area of the shoe and the size provides perfect coverage for most blisters. Most commonly used for blisters under the ball of the foot, top of the toes and edge blisters. Everything the 4-Pack offers and a little bit more. Our most popular product - great value!
