Adhesive

Does applying glue make it stick firmly? NONONO

Water-based adhesive is an eco-friendly alternative to traditional solvent-based adhesives. Solvent-based adhesives contain organic solvents such as toluene and acetone, which produce a sharp odor, are difficult to clean (requiring gasoline or nail polish remover), and release VOCs that pollute the air and harm health. In contrast, water-based adhesive uses water as its base, emits mainly water vapor, has almost no smell, and contains very low levels of VOCs. If it gets on your hands or the floor, simply rinse it off with water. Although it dries a bit slower and is not suitable for water-sensitive materials, it works excellently on porous materials like fabric, leather, paper, and certain plastics. Water-based adhesives are now widely used in sneakers, backpack straps, sofas, wallpapers, and many other everyday items, making them a true “green bonding expert” in modern industry.

In addition to soaking, sun exposure, and vigorous brushing, there are several hidden "glue killers" in shoe care: storing shoes in high temperatures for long periods, crushing the heel to wear them as slippers, and using hard glues like 502 (super glue) for DIY repairs. These practices also silently damage the shoe sole glue, leading to delamination and brittleness. This article points out these mistakes and their causes, and provides gentle and correct care methods.

Many people have the habit of caring for their shoes by soaking them in hot water, exposing them to direct sunlight, baking them on radiators, or even scrubbing them vigorously with strong detergents—but these practices are actually quietly “killing” the glue on the shoe soles. This article points out several common but incorrect shoe care methods, explains why they accelerate glue aging, make it brittle, and cause it to fail, and provides gentle, correct alternatives to help extend the life of your beloved shoes.

Cold bonded shoes rely primarily on high-quality glue to bond the sole to the upper, requiring no stitching or high-temperature vulcanization. The glue acts as the shoe’s "invisible skeleton", and its correct application directly determines durability. During the process, attention must be paid to cleaning, even glue application, pressure fixation, and full curing. In daily use, avoid soaking and direct sunlight. If the glue comes apart, timely re-gluing can effectively extend the life of your beloved shoes.
