New Moto Guzzi Door Mats Available Now
Contact cement is tough because the sole has not completely come apart. I think I'll go urethane part as I'll need a syringe type applicator. It's sad that boot quality on this brand has come to this. I doubt writing to company would do any good.
I guess taking the boots to a boot/shoe repair shop wouldn't be "The Guzzi Way"...
Contact cement. Clean with a brush and alcohol, let dry completely. paint the contact cement onto both surfaces and let it partially dry. Use flat wood on the sole and a jar lid inside the boot and clamp tightly with a big C-clamp. Let cure for 2 days before removing the clamp. T'werks good for me.
