Frequently Asked Questions
Real questions from real buyers — answered honestly
Which insole material is most breathable?
Hipoly is the most breathable, with a true through-ventilation open-cell structure that keeps feet dry and anti-odor.
Are the holes on PU insoles for ventilation?
The back holes on PU mainly reduce weight and prevent deformation. PU is not the most breathable material — for real ventilation, choose Hipoly.
Which material is best for wet environment / rain shoes?
EVA is fully waterproof and Hipoly is moisture-resistant — both are excellent for wet and rainy markets.
How to choose insole thickness?
It depends on the shoe type and use: 3-6 mm for light daily use, 8-14 mm for cushioning and standing, and thicker for comfort slippers. We can match your shoe model.
Will memory foam collapse easily?
Lower-density foam collapses faster. We use controlled, higher density and strict QC to extend rebound life.
