All my trail runners start shredding behind my heels long before the tread or upper gives. Clever sales folks tell me it’s the way I take them off, namely “Left toe pushed down on back of right heel with laces still tight and foot tugged out”. But this not the case. I even use a shoe horn.
So, does anyone know of a ‘hack’ or some nifty tape that won’t turn into a sticky gloop once wet?
I permanently remove my running shoes as they said not to do it …and never had this issue before.
You could try some wetsuit glue or Aquaseal…it dries to a very flexible water resistant layer. I have used it on numerous diving BCD’s and gear repairs and it has held up.
Just make sure you apply a thin layer without any prominent ridges, as this might lead to some undesirable chafing.
