Yes sure we can fix your soles ... thats all gone a bit rotten, we'll remove it all so you are right back to the leather, run a new edge around, build up the height with soft light material and then put a grippy harder wearing sole right thru on the bottom, with no joins so you wont get any splits ... now you've been into our store before ....
1 Record Height Heel and Sole
Eg H=30, S=10
Heel will be, rand 4+ 2 layers 10 eva plus 6 Zephir = 30mm
Sole will be Rand 4+ Soft 6=10mm
1 Full sole EVA if height needed
2 Full sole Soft
3 Heel wedge EVA as needed for height, use a 10mm first.
4 Heel rubber if needed
Dig right around with wide flat screw driver, then pull off by hand or with pincers.
Yellow Glue - leather to resin rand.
Run rand clockwise, move around shoe as you do it. Join on "inside" near back
Keep shape of shoe, don't allow the EVA to flatten the shoe out.
Yellow Glue.
Take almost none off at heel
Remove almost all at front of wedge
Grind wedge flat so shoe sits flat.
While you are putting on blocks of EVA, you are then grinding them to
wedge shapes as you build up layers.
