Which glue works on shoes?
Which glue works on shoes?
A flexible shoe repair adhesive — polyurethane or a neoprene contact cement — never superglue, which cracks within a day of walking.
A sole bond flexes several thousand times a day and is loaded almost entirely in peel, which is the worst case for any adhesive — so the useful products are the flexible ones, and rigid strength on the tube is irrelevant. Preparation does more than product choice: sole units are moulded with release agents still on them and often carry a wax or silicone finish, so abrading and degreasing is what separates a repair that lasts a year from one that lasts a week. Contact adhesives also need pressure rather than time; the joint should be squeezed hard, ideally with a clamp or weight overnight, because the bond is formed at the moment the two coated faces are pressed together.
The options, ranked
| Option | Good at | Bad at |
|---|---|---|
| Urethane shoe repair adhesive | Stays rubbery, waterproof and abrasion-resistant, and can be built up to fill a worn patch. | Cures slowly, typically overnight, and stringy to apply neatly. |
| Neoprene contact cement | What cobblers use: instant grab across the whole sole area and permanent once pressed. | One chance to place the sole correctly, and solvent versions need ventilation. |
| Cyanoacrylate | Convenient for tacking a tiny loose flap of trim. | Rigid, so it shatters at the first flex of the sole and often makes a proper repair harder. |
| A cobbler | Can stitch as well as bond, and can replace the sole outright on a welted shoe. | Costs more than a tube, and is not worth it on a cemented trainer. |
Technique that changes the outcome
- Clean out grit, then abrade both faces with 80-120 grit until the shine is gone
- Wipe with isopropanol or acetone and let it flash off completely
- Apply a thin coat to both faces, wait until touch-dry, then press hard and clamp
- Weight or clamp overnight and leave a further day before wearing them in the wet
What goes wrong
- Superglue on a sole — brittle, and it contaminates the surface for a proper repair later
- Expanding polyurethane glue, which foams the sole away from the upper
- Wearing the shoes before the adhesive has fully cured
Compiled practical guidance rather than a published standard. Product formulations vary by brand and market, so read the label — and where the work is structural, electrical or gas, the regulations that apply where you are govern rather than anything here.
Other glue and adhesive questions
| For | Use |
|---|---|
| Plastic | It depends entirely on which plastic — identify it first, because solvent cement is unbeatable on some and useless on others. |
| Polypropylene and polyethylene | Ordinary adhesives cannot wet these plastics at all. Use a polyolefin primer with cyanoacrylate, an MMA structural adhesive, or weld the plastic. |
| Wood | PVA wood glue for anything indoors; a water-resistant grade (Type I / D4) or polyurethane for anything that gets wet. |
| Metal | Two-part epoxy for anything structural, cyanoacrylate for small dry parts, and MMA where the surface cannot be properly prepared. |
| Ceramic and pottery | Two-part epoxy for anything that will be handled or loaded, cyanoacrylate for a clean break on a display piece — and neither is dishwasher-proof. |
| Fabric | A washable fabric adhesive or a fusible bonding web — and never superglue, which reacts with cotton violently enough to burn. |
| Glass | UV-cure glass adhesive for an invisible joint, clear epoxy where it must hold load, and neutral-cure silicone where it must stay flexible or wet. |
| PVC pipe | PVC solvent cement with its matching primer — and PVC, CPVC and ABS cements are not interchangeable. |
| Tiles | A cement-based thin-set in almost every case; ready-mixed tub adhesive only on small dry walls, never on floors or in showers. |
| Phone screens | A pre-cut adhesive gasket, or a flexible B-7000-type adhesive around the frame — superglue destroys screens and is the classic mistake. |
| Rubber | Contact cement for large flexible areas and rubber-toughened cyanoacrylate for small ones — but silicone and EPDM need a primer or they will not bond at all. |
| Outdoor and waterproof joints | Polyurethane or epoxy for rigid joints, MS polymer where the joint has to move — and check the water-resistance class rather than the word "waterproof". |
| Acrylic (Perspex, Plexiglas) | A solvent cement run into the joint by capillary action — not a tube adhesive, which will always look like a repair. |
| Concrete | Epoxy or a construction adhesive for bonding to it, and a chemical anchor resin — not glue — for anything that carries load. |
| Leather | Contact cement for a permanent flexible bond, or a leather-craft PVA to hold pieces while you stitch them. |
| Silicone | Effectively only more silicone, and even that needs a primer — and any silicone residue left on a surface stops everything else sticking too. |
| Paper | A glue stick or PVA for everyday work; wheat starch paste or methylcellulose for anything you want to survive — and never tape. |
| Foam | A foam-safe water-based adhesive or low-temperature hot melt — solvent adhesives dissolve polystyrene on contact. |
| Polycarbonate | A urethane or silicone adhesive is safest; solvent cements work but polycarbonate is unusually prone to stress cracking days later. |
