Just wondering if others have the problem with running shoes (especially high end Asics with light weight material) wearing through within 150kms.

in the same location of my outer heel a little hole wears through to the inner material (and eventially the plasticky stuff) within 150-200kms.

Does anyone else have this problem? any solutions to fix? I have tried various sizes, wearing two pairs of socks and now using strapping tape on the shoe!!!

any help would be great as i want at least 700-1000 kms out of my shoes.

I've had this problem in the Kayanos too.

In all their top-end shoes, Asics use an extremely rigid "trustic system" through the midfoot to create a "stable platform for propulsion". Some people find this causes them to slip in the heel as the foot moves independantly to the shoe.

Mizuno use a 2 piece upper in the Creation and Nirvana to hold the rearfoot separately and allows the shoes to "gape" at a designated spot on the side of the shoe, instead of at the heel.

The heel counter also plays a big role. Some shoes like the Brooks Trance and Saucony Hurricane & Triumph have a less intrussive external heel counter but the trick is to find the one that works best for you.

A pretty cool trick to stop the slipping:

• Undo the laces from the top 3 holes on either side
  
• Cross up to the very top hole
  
• Come back down one hole on the same side to create a loop
  
• Thread the opposite tail through the loop
  
• Pull tight and tie up

You will be left with an empty lace hole on either side - pull them apart and the shoe will gape at that spot instead of at the heel.

this is caused by the angle of your forefoot causing your heel to move either sideways or to rotate and drag off the fabric inside the heel counter,if you have no other problems/injuries it is easily solved with a small wedge,as a general rule(without having seen your foot)if you  have a stiff high arched foot you wedge under the little toe joint if you have a low arched mobile foot you wedge under the big toe joint,very simplistic and effective,the other option is to wear softer less controlling shoes which move with you,as duffman says the mizuno is a good option for you as some of their models are soft and let you move around-briz

In otherwords a standard lace-lock but not using the last loop holes?

Sort of, its a modified lace lock. Main difference being you tighten from the top hole, and you leave one or two holes beneath the lock for the shoe to gape.

The wedges Brizza is talking about are very specific to the forefoot to rearfoot relationship so you wont find them in stores (FF varus/valgus wedges have to be within 2degs of the deformity to be effective). If you book in to see a good sports Pod or Physio, they can customise a device like this for you to help limit any excessive rearfoot motion

Thanks Duffman - i will try the modified lace lock and also use (on research from previous coolrunnings threads i have found on issue) seude heel patches ($4 from coles) for this specific purpose.
