A separated shoe sole stays put when both surfaces are cleaned, degreased, coated with a thin layer of flexible shoe adhesive, pressed together, and left clamped for a full 24 hours.
For the full breakdown, see our best Glue for Shoe Soles guide.
A flapping sole ruins a walk fast, and most people reach for a thick blob of glue before fixing the actual problem. The repair holds only when the surfaces are clean, dry, and free of old adhesive, and when the shoe is left alone long enough for the bond to cure. Skip either one and the sole peels again within a week. The job takes about 15 minutes of hands-on work plus a day of waiting.
What You Need Before You Start
Gather a flexible shoe adhesive, rubbing alcohol, a clean cloth or soft brush, something to roughen the surface, and clamps, tape, or rubber bands. Read the tube before opening. Bostik’s technical data sheet says its adhesive is flammable, so work ventilated with no ignition sources, and wear gloves. Loctite recommends room temperature, since cold glue grips poorly.
- Shoe adhesive — flexible, made for footwear, not super glue
- Rubbing alcohol — for greasy or oily spots
- Sandpaper or a rough cloth — only if the adhesive instructions call for it
- Clamps, tape, or rubber bands — to hold the sole while it cures
- Gloves — the adhesive bonds skin just as well as rubber
The Step Order That Makes the Bond Hold
Clean and dry both surfaces first, apply a thin even layer of adhesive to the surface the product specifies, press the sole on with edges aligned, and hold it under pressure for the full cure time. Every manufacturer guide reviewed leads with the same first move: get rid of the dirt and old glue.
- Clear the debris. Wipe away loose dirt with a dry cloth or soft brush, and pull off any old adhesive.
- Degrease and dry. Dab rubbing alcohol on greasy areas, then let both surfaces dry completely. Damp surfaces kill the bond.
- Roughen if directed. Some adhesives want a scuffed surface; check instructions before skipping or adding this step.
- Apply a thin layer. A thin, even coat beats a thick blob. Too much glue traps air and never fully cures.
- Align and press. Line the sole up, then press firmly. Bostik calls for holding at least 5 seconds for the initial grab, then working even pressure across the whole area.
- Clamp it. Rubber bands, tape, or clamps keep the sole tight against the upper while the adhesive sets.
- Wait the full cure. Leave the shoe undisturbed for at least 24 hours, sometimes 24 to 48 depending on the product, in a dry, ventilated spot away from direct heat and sunlight.
Done right, the sole sits flush with no gap or spring when pressed, and the shoe is ready once the cure time is up.
Choosing the right adhesive matters as much as the steps. If you’re not sure which formula suits leather, rubber, or a glued synthetic midsole, this comparison of glues for shoe soles sorts out which fits your pair.
How Long Until You Can Wear Them Again?
Plan on a full day, or two for some products. Walking on it early is the fastest way to undo the repair.
| Product Guidance | Time To Leave It | Note |
|---|---|---|
| Bostik shoe repair adhesive | At least 24 hours | Dry, ventilated area away from heat and sun |
| Loctite shoe glue guidance | 24 to 48 hours | Secure with rubber bands, tape, or clamps |
| Initial grab hold | 5 seconds of pressure | Then even pressure across the whole area |
| Bostik tech sheet | Flammable, ventilated use | Gloves advisable, no ignition sources |
| Loctite application | Thin layer, one surface | Press together quickly after applying |
| Working temperature | Room temperature | Cold conditions weaken the bond |
Why Most Sole Repairs Fail
Nearly every failed repair traces back to skipping cleaning, using the wrong amount of adhesive, or pulling the shoe out of the clamp too soon. Old glue, oil, and moisture cut bond strength, which is why Bostik’s technical data sheet insists surfaces be clean, dry, and free of dust, dirt, and oil before any adhesive touches them.
No single adhesive suits every shoe material, and products disagree on whether to bond immediately or wait for a tack time. Follow the tube’s directions over any general advice, including the steps above.

Common Questions
Can I use super glue on a separated sole?
Super glue dries hard and brittle, so it cracks as the shoe flexes. A flexible shoe adhesive bends with the sole and holds far longer. If super glue is all you have, it may hold briefly, but expect the sole to peel again soon.
Do I really need to clamp the shoe?
Pressure keeps the sole tight against the upper while the adhesive sets, and without it gaps form that weaken the bond. Rubber bands, tape, or clamps all work. Don’t clamp so hard that you dent the sole or squeeze all the adhesive out.
What if the sole is torn, not just lifting?
A sole that’s cracked through or missing chunks of rubber is usually beyond glue. Adhesive reattaches a sole that’s separated but intact. Once the rubber itself is torn, a cobbler or a replacement pair is the more honest answer than another layer of glue.
