Sole hydrolysis: the facts
Meindl uses a number of different soles on their boots, including Vibram. The material used in the midsoles sometimes undergoes a chemical process called hydrolysis, which can make the midsole material fail. This can occur on all makes of boots. Here are some of the most frequently asked questions about hydrolysis – and how to avoid it:
What happens to the boot?
Hydrolysis causes two main issues – the sole material crumbling away, or the sole separating from the boot.
Why does this happen?
The number one cause is lack of use.
The midsole materials must be regularly compressed and released to shift fresh air through them. When left in storage for extended periods, the sole material goes brittle, and it can fail. Rather in the way rubber will perish after a time.
This is intensified by storing the boots before they are fully dry, and storing them in damp or humid conditions.
Top tips to avoid hydrolysis through lack of use:
- Wear them regularly
- Avoid long periods of storage
- Always fully dry your boots before storing them for any length of time
- Store your boots in dry conditions
