This is about my own shoe repair for the outer sole separated... This is a Clarks - Gore-tex . これは、剥がれてしまったアウターソールの靴の修理についてです。これは、クラークスのゴアテックスです。

It challenging to sew the outer sole as the rubber is thin, old material need additional care to stitching as the rubber is "weak/ soft". hence need additional care to pull the thread. ゴムが薄いため、アウターソールを縫うのは困難です。古い素材はゴムが「弱く/柔らかい」ため、縫製にさらに注意が必要です。したがって、糸を引っ張る際にはさらに注意が必要です。

The care required make it more interesting and new strategy and method is necessary to improve. より興味深いものにするためには注意が必要であり、改善するには新しい戦略と方法が必要です。

With top sole lining layer remove and see the inner sole with stitch line visible at edge.

Measure the shoe inside depth and reference point to mark where to cut a line on the rubber outer sole for hiding stitching thread.

The purpose is to approximate where the external cut line closer to the inner sole section.

This is to help locate the needle insertion point.

Use ruler to check location to cut a line for hiding stitching thread.

Before start repair is to clean the inside layer, then apply glue on the inner and outer sole layer.

Ensure to allow sufficient curing time for the glue to cure before attaching them. Try to use mallet to apply pressure when doing this process.

Once you have allow sufficient time for glue to harden before start stitching process. The main reason for stitching thread is to hold the two layer better and minimize stress. This is help reduce stress to the glue adhesion.

It is important not to cut too deep line, just sufficient depth to conceal the thread.

Dip thread one end to glue to minimize end frail when doing stitching work with needle.

check to check is the awl tool of sufficient length.

Mark the spacing in between stitch point.

Cut line on outer sole to hide thread.

Use compass to mark location for insert needle awl.

This is to show the needle awl insertion point and decide how much cut line to extend.

Repeat the same for other side of the shoe.

Lady Shoe repair "KLEI"

Lady shoe repair task

This lady shoe with the bottom sole being defective. Most common problem found on most shoe repair is the separation of outer sole. Both the left and right shoe have the same issue of outer sole split wide open.

Based on my observation for some reason the outer sole have the glue " missing" or the adhesion surface on both the surface is lacking.

Hence the bondage between outer sole to the base is " disappear" and the result the sole just does not stick together.

This is a customize shoe have it outer sole separated, can see the felt material is also lifted off.

What most surprising is the shoe is hardly worn or stress out base on my observation.

For some reason this shoe is barely use or worn by user but have this defect appear so early.

After checking the inner sole and inner lining material it feel strange and later discovered the material use for lining inside gradually disintegrate when working on both shoe.

Not sure why the material behave this way, base on observation and feedback this shoe was hardly worn. So not sure why the lining react this way.😂

Underside view of inner sole and notice the wrinkle toward the toe tip. It is not even surface due to external transparent layer is lifted out. Not sure what is the reason for this surface.

The brand name imprint on inner sole as KLEI.

Notice the material use for this shoe is started to peel off. The clear transparent layer is separated with the black base. The black base where some it material is dropping off. Can see the broken black material is disintegrating, see the black spot on the cardboard surface.

Any way try to apply glue between them to see it work or not. The result is not very good as the glue have poor outcome.

Certain part of the felt material was lifted up is re attached with contact glue.

It best to ensure the glue is allow with sufficient time to cure before stick both piece together.

This the learning experience and and also trial an error over time.

If the glue is allow to cure it adhesion is better and your repair work is more satisfactory and enjoy the repair work.

As noted the old glue need to clean the outer sole surface, notice the old glue is best to remove and clean surface before apply glue.

This is to show what happen when try to lift off the inner

sole. The top layer disintegrate when touch it surface with bare hand.

Not sure why this material behave in this manner.

Allow glue to cure time before attached both layer together.

Try to do stitching for the toe side section . However because the inner lining and inner sole materials is very fragile just try out only to the toe to give strength .

Hence limited edge of the outer sole use the thread stitching because of this issue

This complete repair for this shoe.

Repair shoe of kid

Today project is on shoe repair for kid (grand daughter).

7th March 2022

This project is on kid shoe repair.

The bottom sole is defective, the bottom/outer sole is detached for both right and left shoe.

Both right and left kid shoe with it bottom/outer sole detached.

Check on status of defect, in this case the bottom/outer sole is "open" or detached.

It is a good idea to verify is there any other defect on shoe.

Inspect and verify issue for the other side of shoe. Same issue with bottom /outer sole detached.

Use a brush to remove to dirt on both bottom outer sole surface (yellow sponge) and the shoe insole surface (paper interface).

Sand paper is use to clean old glue traces and and remove loose dirt.

Update on 10th March 2022.

Some of tools and materials used for this repair.

Sand paper to clean the surface before apply glue.

Apply glue to outer sole surface. Allow sufficient time to cure glue before attach both surface.

Take note, this is a slight mistake on this shoe repair. The thread are expose on outside surface. Another point if punch hole between yellow and grey layer it is possible it might split..

Recommend to remove the outer most sole (jagged blue layer).

And punch hole with stitches sewing awl ( Special sharp pointed tip to hook) thru the grey/yellow foam layer.

See other picture below for more details.

Pre-glue preparation.

This is the outer most sole , remove old glue and clean surface.

Use sharp tool like pointed awl, knife edge to remove dirt and old glue material surface.

This is an important step to help good adhesion between two layer.

To roughen the surface area, use this "spiky" tools.

Use awl to pierce hole before inserting stitching sewing awl.

At time the sole material are harder material, pre punch hole is less "stressful" for the stitching sewing awl tips.

Tips:- stitching thread from bottom is better way to "hide"threads ,if stitch thread from the side way the thread is visible.

Stitching sewing awl inserted, do take note of the inner sole where the tips is position.

To minimize piercing other part of shoe, check status from time to time when inserting tool.

When pulling stitching sewing awl do take care of the sharp tips..

This is an example for the heel area.

Pull on other end of thread to create a loop sufficient to thread pass thru.

Tips. the first loop it recommend to tie knot with other thread end.. to terminate is the pull the thread and trim excess thread and use lighter to melt it end.

insert a thread thru loop. Once it is ready tighten the loop thread .

Make a thread loop on inside to catch the stitching sewing awl hook.

You need to have some tension on both side, one is to pull thread away position and the other is pull awl handle away in the opposite direction.

Close up view on how the thread loop catch the awl hook.

Re stitch the broken strap, use normal sewing thread and needle to repair.

Compare the top shoe where the thread is hidden. do take note to help and guide have use pen to mark line on both edge when re attached the blue outer most sole to the grey layer.
