Why do i wear out the heels on the INSIDE of my shoes?

Sounds like pronation. The inside portion of the heel is hitting the ground first, being forced into a neutral position, and the innner heel is being worn away from the friction between the material in the heel and your sock.

A shoe guy might tell you different, but my guess would be that you should find a shoe with LESS motion control, so that the inside heel will compress more, thus not being forced to rub up against your sock.

weird that the old nike structure triax 8 didn't wear on me, but everything else does, asics, saucony, etc.

Fabric vs. (p)leather maybe?

Holland is right. The inside tears from excessive friction usually caused by pronation.

Without question, it is pronation. My guess is that if you look closely, you wear out the ball of the foot area of the shoe more than the outside part in the front. If you've run in a shoe in which this doesn't happen, that's a shoe that has some kind of bridge, making overpronation difficult. All this is no problem, as long as you're not experiencing knee pain.

guess i should have been clearer...what i meant by INSIDE was not the outside, as in the outside of the shoe as in the part you see. what you cannot see, the inside, in the back where my heel sits, wears out quickly. i do not rub against it excessively and i have no idea what is going on? it's directly behind my heel where it touches my shoe on the INTERIOR! thats the word i should have used!!!

Any luc luck

Could be that the shoe is to loose around your heel. Try doing a different lacing pattern to lock your heel in. You can either move your laces back to the furthest back hole at the top or double back the laces to the farthest back hole to make loops then take the excess lace and cross them over to use the loops instead of a hole to lace the shoes tight. Either one of those should lock the heel in better. That will limit the up and down movement of the heel and limit the friction on the inside of the shoe.

Have the same problem, and have since I was a kid. And it's not heal slippage.

The reason is that you walk like a duck. Let me tell you that this will shred you knees eventually and using a shoe to try and stop this is akin to putting new tires on a banger and expecting performance.

it goes all the way to the core of the shoe where my heelbone (if that exists)touches the rear of my shoe. it basically rubs enough and wears to give me a blister. i cannot find a pair of shoes that i can not wearout?

Please refrain from telling people who walk like a duck or like a pigeon to straighten their step.

Stop doing this.

STOP.

If they have femoral anteversion or tibial torsion, the only thing you will achieve is exactly the thing you're trying to avoid: to wreck their knees.

Try Heel Hole from Shoe Armour. It prevents holes in the heel of your shoe. The link is below:

Good advice already given above, try a different lacing to lock your heel in better. Also make sure you aren't ordering a half size too large.

It could be caused by your stride too though. Can you upload a video of you running? If you are excessively heel striking and "rolling" over your foot, it could cause your heel to move up and down in the shoe every stride. Likewise, if you are pointing your toes too much, you may be causing the back of the shoe to drop down off your heel, although there wouldn't be much pressure at the heel, so this would be more likely to cause blisters than cause the shoe to wear out.

He said inside of shoe hill not outside. Why don't people read? Holes are outside of shoe. Heel inside are just torn fabric that hurts the heel eventually and cause blisters. I just can't understand why you don't understand even after he said this.

Guess, I should of checked your link first. Sorry, for that. It shows for inside heel. My bad. I said to read first but I should of checked your link first before replying.

I have had the same problem for about 3 years and I am not a runner. But, i still wear expensive running shoes and still go through them before the are even worn in good. it really is horrible because i will spend $125 on a pari of sneakers and the heal get worn done to the plastic before they are even 1/2 way worn out. i decided to research this and came to your question. did you get an answer? i was wondering if you take off your sneakers with the other foot - sort of your toes pulling the shoes off of your heel. i have been wondering if that could be it. i am just out of ideas! doesnt happen on any other shoes except sneakers.

I have the same issue of wearing out the interior heel box. It wears out the cushion within the first few days of running in new shoes. I have had the issue the last 5+ years. Since that time, I have developed a knee injury and back pain. I did not have the issue when I wore a support shoe for my neutral/pronating semi-narrow foot with skinny ankles. I have tried different lacing techniques, inserts, different strides, etc. Nothing seems to work. I have had my stride analyzed & so far, a whole lot of nothing.

I would love to find out how to fix this very expensive issue that might also be leading to other problems.

Heel striking probably has your heel working against the fabric there. It's not abnormal for shoes to wear through there, just maybe not that quickly.
