Like to know how this shoe has this problem?
I guess it may be cause by over stretching when the leather is not properly hydrated and fatliquored.
That resulted in breaking up the inter-locking leather fibrils that also weaken the leather structure.
This is my recommendation:
Phase 1: - Leather rejuvenates in conjunction to stretch the leather to conform to the desired configuration for wearing comfort.
The leather has to be soaked damp easier from the inside and also through the damaged areas.
This will cause the leather to relax and easier to be stretch to the desired configuration or shape of the foot.
When the leather is equally stretched and not concentrated only in that small area; it is then fatliquored for suppleness with strength and softness.
Two products is required in this process namely; the Hydrator-3.3 and Fatliquor-5.0.
Phase 2: - Repair to the damaged leather “structure” with Impregnator-26 that will impregnate micro cracks fills and tightens that is film forming to strengthen and becomes part of the leather structure.
Phase 3: - The leather has to be prep for repair and refinishing accordingly depending on what has been used before.
An alcohol stripping may be necessary if solid wax has been used.
Otherwise Prep-7.7 may be used as prep to remove all foreign contamination including conditioners to the raw leather finish.
Surface repair requires Leather Bond-3D in conjunction with matching black to original coloring with a transparent dye using Aniline Dye-63, a translucent Dye using Anitque-26 or a opaque micro color using Pigment Micro-54.
This is done with in between leveling and compressing with Leather Spatula-6, blow drying and fine sanding (1000 to 1500 grit).
It is worked until the cracks are smooth.
Phase 4: Color Coating.
From high-end transparent dye, medium translucent hybrid to low-end opaque micro-pigment has to be determined to match the original.
Phase 5: Gloss, Satin or Matte Top Coating.
For transparent Aniline Dye-63 either used Topcoat Aniline-79Gloss or Topcoat Aniline-53Waxy Matte.
For translucent Dye Antique-26 and Pigment Micro-54 used Topcoat Micro-72Gloss
