Choosing the Right Glue for Insoles

The success of your insole repair hinges on selecting the right adhesive. Not all glues are created equal, and some are better suited for the demands of footwear. You need something that can withstand flexing, moisture, and the general wear and tear of walking.

Recommended Glues:

Contact Cement: This is the gold standard for shoe repair. It creates a strong, flexible bond that’s resistant to water and temperature changes. Contact cement bonds instantly upon contact, so precise placement is key.
Shoe Goo: A popular choice for its versatility and durability. Shoe Goo is a rubber-based adhesive that’s ideal for repairing soles, seams, and, of course, insoles. It offers excellent water resistance and flexibility.
Rubber Cement: A more affordable option, rubber cement is suitable for less demanding repairs. It’s flexible and easy to apply but may not be as durable as contact cement or Shoe Goo.
Polyurethane Glue: This type of glue expands as it dries, creating a strong bond. It’s excellent for filling gaps and bonding different materials, but it can be messy if not applied carefully.

Glues to Avoid:

Super Glue (Cyanoacrylate): While it bonds quickly, super glue is brittle and doesn’t offer the flexibility needed for insoles. It’s prone to cracking and failing under stress.
Hot Glue: Hot glue isn’t durable enough for the constant flexing and wear of shoes. It can soften and lose its bond in warm conditions.
Wood Glue: Wood glue is designed for porous materials like wood and isn’t suitable for the materials typically found in shoes.

Gathering Your Supplies

Before you start, gather all the necessary tools and materials. Having everything ready will make the process smoother and more efficient. (See Also: Will Insoles Help My Ankle Pain )

Essential Supplies:

The Correct Glue: Based on the recommendations above, select your adhesive. Contact cement, Shoe Goo, or rubber cement are all good choices.
Old Insoles (optional): If the original insoles are beyond repair, measure and trace the old insoles onto new ones. You can buy replacement insoles at most shoe stores or online.
Cleaning Supplies: You’ll need a brush or cloth to clean the shoe and insole surfaces.
Solvent/Cleaner: Acetone or rubbing alcohol will help remove any old glue residue and prepare the surfaces for bonding.
Applicator: A small brush, toothpick, or the applicator tip that comes with the glue.
Clamps or Weights: To hold the insole in place while the glue dries.
Scissors or Utility Knife: For trimming any excess insole material.
Gloves: To protect your hands from the glue.
Ventilation: Work in a well-ventilated area to avoid inhaling fumes from the glue.

Optional Supplies:

Sandpaper: For lightly roughing up the surfaces to improve adhesion.
Masking Tape: To protect the surrounding areas of the shoe from glue.
Cotton Swabs: For precise glue application.

Preparing Your Shoes for Insole Replacement

Preparation is key to a successful repair. Take your time with these steps to ensure a strong and lasting bond.

Step-by-Step Preparation:

Remove the Old Insoles: If the insoles are loose or partially detached, gently remove them. If they’re firmly attached, you may need to pry them out carefully using a flat tool.
Clean the Shoe Interior: Use a brush or cloth to remove any loose dirt, debris, or old glue residue from the shoe’s interior. A clean surface is essential for good adhesion.
Clean the Insoles: If you’re reusing the original insoles, clean them thoroughly. Use a brush and solvent (like acetone or rubbing alcohol) to remove any remaining glue or dirt.
Rough Up the Surfaces (Optional): Lightly sand the surfaces of both the shoe interior and the insole to create a slightly rough texture. This will improve the bond. Be careful not to damage the shoe’s materials.
Test Fit the Insoles: Before applying any glue, place the insole back into the shoe to ensure a proper fit. Trim any excess material if necessary.

Applying the Glue: Step-by-Step Instructions

Now comes the crucial part: applying the glue. Follow these steps carefully to achieve a strong and lasting bond.

Contact Cement Application:

Apply Glue to Both Surfaces: Using a brush or the applicator tip, apply a thin, even layer of contact cement to both the shoe interior and the back of the insole. Make sure to cover the entire surface area.
Let the Glue Dry (Important!): Allow the glue to dry completely until it’s tacky to the touch. This usually takes 10-20 minutes, depending on the glue and the environment. The glue should no longer be wet, but it should still feel slightly sticky.
Position the Insole: Carefully align the insole with the shoe interior. Contact cement bonds instantly upon contact, so make sure you have the insole positioned correctly before pressing them together.
Press Firmly: Once the insole is in place, press down firmly and evenly over the entire surface. This will ensure a strong bond. You can use your hands or a rolling pin to apply pressure.
Clamp or Weight (Optional): If possible, clamp the insole in place or place weights on top of the shoe for several hours or overnight. This will help the glue cure properly.
Trim Excess (If Necessary): If any glue oozes out around the edges, wipe it away with a cloth dampened with solvent.

Shoe Goo Application:

Apply Glue to Both Surfaces: Apply a generous amount of Shoe Goo to both the shoe interior and the back of the insole. Ensure complete coverage.
Position the Insole: Carefully align the insole with the shoe interior.
Press Firmly: Press down firmly and evenly over the entire surface.
Remove Excess Glue: Shoe Goo can be messy. Wipe away any excess glue that squeezes out from the edges of the insole with a cloth or cotton swab.
Secure and Allow to Dry: Use clamps or weights to hold the insole in place. Allow the Shoe Goo to dry completely, following the manufacturer’s instructions (usually 24-48 hours).

Rubber Cement Application:

Apply Glue to Both Surfaces: Apply a thin, even layer of rubber cement to both the shoe interior and the back of the insole.
Let the Glue Dry: Allow the glue to dry completely until it’s tacky to the touch.
Position the Insole: Carefully align the insole with the shoe interior.
Press Firmly: Press down firmly and evenly over the entire surface.
Secure and Allow to Dry: Use clamps or weights to hold the insole in place. Allow the rubber cement to dry for several hours.

Polyurethane Glue Application:

Apply Glue to One Surface: Apply a thin, even layer of polyurethane glue to either the shoe interior or the back of the insole.
Position the Insole: Carefully align the insole with the shoe interior.
Press Firmly: Press down firmly and evenly over the entire surface.
Clamp or Weight: Use clamps or weights to hold the insole in place while the glue expands and cures (follow manufacturer instructions, usually several hours).
Remove Excess Glue: Polyurethane glue expands as it dries. Wipe away any excess glue with a damp cloth before it dries.

Curing and Aftercare

Once the glue is applied and the insole is in place, proper curing and aftercare are essential for a durable repair.

Curing Time:

The curing time varies depending on the type of glue used. Always follow the manufacturer’s instructions on the glue packaging. Generally, allow the following: (See Also: Will Insoles Make My Shoes Fit )

Contact Cement: Allow at least 24 hours for the glue to fully cure before wearing the shoes.
Shoe Goo: Allow 24-48 hours for the glue to cure completely.
Rubber Cement: Allow several hours for the glue to dry.
Polyurethane Glue: Follow the manufacturer’s instructions, usually several hours.

Aftercare Tips:

Avoid Excessive Moisture: While most glues are water-resistant, it’s best to avoid exposing the repaired shoes to excessive moisture, especially during the curing period.
Gradual Wear: Start by wearing the shoes for short periods to test the repair. Gradually increase the wear time as the glue fully cures.
Inspect Regularly: Check the insole periodically for any signs of loosening or wear.
