My running shoes always wear on the outside midfoot part of the sole. I have put 73 miles on my newest pair (Saucony Guide 5) and the white part is already starting to show. I only weigh 120 lbs. Any suggestions either for shoes with a more durable sole or a way to extend the life of my shoes?
I have issues with shoes like the Guide and Kayano that don't "fill the gap" underneath the cuboid bone. That's where the outside midfoot hits the ground.
Put some cushion underneath there not plastic!
Your foot wears through this part quickly. Try Nike or Brooks, they do a good job with this part of the shoe. Try the Zoom Structure or Trance
If you are wearing them that quickly on the outside is sound like you are most likely in the wrong shoe. Were you fitted for them at a specialty store? If not, go to one and have them see what is going on.
Saucony's shoes are notorious for wearing down quickly. The soft midsole foams and blown rubber outsoles give the shoes a nice feel in-store, but do nothing in the way of durability. I'd recommend any other brand over Saucony. Even if you're in the wrong general category, there's no reason your shoes should wear down so fast.
I run 50 miles/week completely barefoot and I never need to change running shoes. You probably run faster and more than I do, but if a regular hobby jogger like me can do this then there is no reason why you should be wearing down your shoes that fast. It is caused by the way you run and no pair of shoes is gonna fix that.
Your dilemma is like deciding which brand of powdered sugar to put on a turd. Enjoy your turd dude!
