Footwear serves as more than just a fashion statement. It's an essential tool for protecting our feet and providing comfort during daily activities. However, even the sturdiest of shoes are not immune to the effects of hydrolysis – a chemical process that can slowly deteriorate the materials of your favourite pair. In this blog post, we'll delve into what hydrolysis is, its impact on footwear, and most importantly, how you can safeguard your shoes from its damaging effects.
What is Hydrolysis in Footwear?
Hydrolysis is a chemical reaction where water molecules break down the molecular bonds of certain materials, leading to their degradation or weakening. In the context of footwear, this process primarily affects materials such as rubber, foam, and adhesives – common components found in shoes.
The Impact of Hydrolysis on Footwear
Hydrolysis can manifest in various ways within footwear:
Outsole Degradation: The outsole, typically made of rubber, is prone to becoming brittle, cracking, or losing its grip due to hydrolysis.
Midsole Deterioration: Foam midsoles, like EVA or PU, may lose their cushioning properties, compress, or disintegrate when exposed to moisture and high temperatures.
Adhesive Weakening: Hydrolysis weakens the adhesive bonds used in footwear construction, leading to layers separating and compromising the shoe's structural integrity.
Ways to Protect Your Shoes from Hydrolysis
Preventing hydrolysis damage requires proactive care and maintenance:
Keep Them Dry: After exposure to moisture, ensure your shoes dry thoroughly before wearing them again. Avoid leaving them wet for extended periods, as this can accelerate hydrolysis.
Proper Storage: Store your footwear in a dry, well-ventilated area away from direct sunlight and moisture. Humid environments like basements should be avoided.
Regular Cleaning: Clean your shoes regularly to remove dirt and debris, which can trap moisture and promote hydrolysis. Use mild soap and water for cleaning and allow them to air dry completely.
Waterproofing: Apply a waterproofing treatment to the outer materials of your shoes, such as the upper and seams, to repel water and reduce moisture penetration.
Monitor Signs of Damage: Keep an eye out for signs of hydrolysis damage, such as cracking, crumbling, or separation of materials. If you notice any it may be time to contact a good repairers or in some cases begin looking for a replacement pair.
Hydrolysis can be a silent but significant threat to the longevity and performance of your footwear. By understanding this chemical process and implementing preventive measures like keeping your shoes dry, proper storage, regular cleaning, waterproofing, and monitoring for damage, you can extend the lifespan of your favourite pairs and continue to enjoy their comfort and support for longer. Remember, a little care can go a long way in preserving your footwear investment.
