A boot sole coming free from your favorite pair of boots can be disheartening. With the proper materials you can repair the boot by reattaching the sole. This will allow you to wear your favorite boots once more. If you use a waterproof adhesive, your repair may last the remaining life of the shoe, making the repair a cost-effective alternative to purchasing a new shoe.
Soak a rag in rubbing alcohol, and clean both the sole of your shoe and the material of your boot. Removing any oils or debris will ensure a proper bond. Allow the alcohol to dry.
Apply waterproof adhesive to the sole where it has come unattached. Apply enough to cover the surface without spilling out the sides.
Place rocks or a weight into the boot to hold the boot and sole together while curing. Allow the boot to set overnight.
