Do the insoles or shoe stretchers exude resin?
14th May 2018
Since these are natural products, it can happen that the shoe stretchers exude resin. This can simply be cleaned off, and there even is an upside to it: The resin contains antibacterial and anti-fungicidal qualities, which even improve the effect of the shoe stretchers.
The insoles do not exude resin, as they are too thin and flexible.
