I`d used Aquasure + Cotol.
Aquasure® Urethane Repair Adhesive & Sealant | McNett Europe - Outdoor and
Cotol-240™plus Cleaner & Cure Accelerator | McNett Europe - Outdoor
when you mix it together (1:1 approx) - it became more liquid, but hardening faster.
I had problem with my turbosole from crashed neoprene. It was hole, where I can put my finger, and it was on the upper side of bridge of the foot
First - using Cotol you can clean all surfaces inside of the hole and around it.
You have to put well mixed Cotol+Aquasure inside the hole on all inner surfaces, and stay hole opened.
Waiting until it became little more solid (it can takes from 10 till 30 min).
Then squeeze it tightly.
Wait again.
Second: After 1-2 hour: Clean all surfaces around glued hole, and glued surface using Cotol. Put new mix of Cotol+Aquasure (old already should be as solid plastic, just throw it away) around the repaired hole with thick layer (1-2 mm) inside and outside of the sock.
Wait more 2-3 hours.
Third - you can repeat *Second* as much as you wish (1-2 times more). Also you can use some nylon stretching fabric, starting from *second*, to put it over the glue on the hole, and put some glue over the fabric. (Fabric should be permeated by the glue).
Size of the fabric should be 2-3 cm more wide of the hole.
Best kind of this fabric you can take from lady's stockings
it it best fit for this kind of repairing.
If it used ones - clean this piece of fabric it with Cotol before usage.
So, I`d made reparing of my turbosole on the nature, using just woodenpieces, aluminium foil (for mixing glue and Cotol), and sun
It is still alive! (over 5 years).
