In short: re-gluing a lifting sole at home works, but the bond often fails; below are the four reasons and how to make it last longer.
A sole with a glue gap can be reglued at home. But at the shop, most pairs brought in have already been glued at least once and come apart again. This article covers both parts: how to do it properly, and why home repairs often do not hold for long.
First, see how the shoe has separated
| Type | Signs | Can you glue it yourself? |
|---|---|---|
| Short gap at the edge | A short section at the toe or side, the rest still firmly attached | Yes |
| Gap longer than half the sole | The sole is detached, with the old glue layer visibly dried and hard | Best brought to a shop |
| Broken stitching | Stitching visibly undone, sole still held by glue | Needs restitching; gluing does not fix it |
| Cracked or broken sole | The sole material has perished or snapped in two | Needs resoling |
Many people glue a pair from group three or four again and again. It is not that the glue is bad, but gluing is not the fix for those two kinds of damage.
How to glue a short gap properly
- Clean and scrape off all the old glue. New glue does not stick to old hardened glue. Scrape both surfaces clean with a blunt tool, then wipe with a dry cloth.
- Roughen the surfaces. Lightly sand both surfaces to be glued with fine sandpaper. Smooth, glossy surfaces hold glue very poorly, and this is the most skipped step.
- Let it dry completely. Any dampness makes the joint weak from the start.
- Apply a thin layer of glue to both surfaces. With contact adhesive, apply to both surfaces and wait for it to go tacky as the instructions say before pressing them together. Applying to one side and pressing straight away is the wrong way to use this kind of glue.
- Press firmly and hold for several hours. Use clamps, rubber bands wrapped around it, or a heavy weight. Pressure and time are what make a lasting joint, not the amount of glue.
- Leave it long enough before wearing. Glue that is dry on the surface has not necessarily reached full strength. Wear the shoes too soon and the joint takes load before it is ready.
Four reasons home glue jobs come apart
1. Skipping cleaning and roughening
This is the most common reason. The glue sticks to the dust and old glue rather than to the sole material. It looks joined, but a few dozen steps are enough to pull it apart.
2. Not pressing hard enough or long enough
Squeezing by hand for a few minutes is not enough. Shoe soles are springy; let go and they bounce back and pull away from the glue before it has hardened.
3. Using the wrong glue
A shoe sole flexes with every step. Hard, brittle glue cracks with each flex. Glue for shoes needs to stay flexible once dry.
4. Gluing when the real damage is elsewhere
If the sole has perished or the stitching has broken, gluing is only a stopgap. The glued spot holds, but the spot next to it keeps opening up.
About 502 super glue
This is something we wish people would not use on shoes, and not only because it does not last.
502 super glue dries very hard and brittle, so it handles flexing poorly and cracks and comes apart within days. But the bigger problem: it soaks into the sole material and leather and hardens there. When the shoes come to the shop, the technician has to clean out that soaked-in glue before they can be reglued, and on leather the glue-soaked area has usually discoloured and gone rough, and cannot be restored.
In short: gluing with 502 makes a proper repair later harder and more expensive. Many pairs reach the shop with a small gap surrounded by a patch of hard glue smeared around it.
When to bring them to the shop
- Long gap, sole almost detached. Needs machine pressing and repositioning to the right shape.
- Broken stitching. Needs stitching, by hand, along the original stitch line.
- Sole perished, cracked or worn through. This is a resoling job.
- Already glued at home and came apart again. The more layers of old glue, the thicker it gets and the harder it is to deal with.
- Leather shoes or valuable shoes. Glue smeared on leather is much harder to remove than the cost of gluing it properly in the first place.
See our shoe repair pricing for the cost of gluing, restitching and resoling. For sports shoes with worn soles there is our dedicated resoling service for pickleball and badminton shoes.
On badminton and pickleball shoes, a lifting sole usually comes with worn tread. If so, see badminton shoe resoling by brand or pickleball shoe resoling by brand.
Not sure which type your pair is? Take a photo of the gap and book online, and we can tell from the photo whether it needs gluing, stitching or new soles, and give you the price upfront.
Frequently asked questions
How long does home regluing hold?
It depends where the gap is and which adhesive you use. A short gap on the side, cleaned properly and clamped tight, holds quite well. A gap at the toe, where the sole flexes most, usually opens again within weeks.
Can I use superglue on a shoe sole?
Better not. It dries hard and brittle while the sole flexes constantly, so the bond cracks and lets go, leaving a hard ridge of glue that makes the next repair harder.
What does the shop charge, and how is it different from doing it yourself?
Regluing a loose sole is 250,000d. The difference is cleaning off the old adhesive and clamping for long enough, the two steps that decide how long the bond lasts. See shoe repair.
The sole has come off almost completely. Can it still be reglued?
If the sole itself is intact, yes. If it has perished, cracked or worn through, it needs replacing; see worn soles.
