The insole is key to footwear comfort, with its material determining comfort, support and breathability. Below are the top 4 popular insole materials, plus how Foamwell elevates the industry with enhanced foam production capacity and an expanded product line.
1. EVA Foam: All-Round Daily Comfort
EVA foam is the most widely used insole fabric—lightweight, soft and cost-effective, offering great cushioning for daily wear and entry-level sports, reducing foot fatigue.
Foamwell has upgraded its EVA foam production capacity with advanced automatic lines, ensuring stable supply for global partners. Our EVA series comes in various densities, and is engineered to resist deformation, solving the issue of traditional EVA collapse.
2. PU Foam: High-Performance All-Day Support
PU foam balances support, durability and cushioning, with superior rebound and density—ideal for long-standing professionals and moderate sports. It also keeps feet dry with good breathability.
Foamwell expanded its PU line to include standard, high-end and eco-friendly (10% recycled) options. Enhanced production capacity (via high-pressure foaming and CNC cutting) ensures large-quantity, high-quality output, plus specialized variants like anti-bacterial PU.
3. Supercritical Foam: Next-Gen Lightweight Performance
Supercritical foam uses high-pressure CO₂ or nitrogen to create uniform microcellular structure, delivering lightweight, high-rebound, durable comfort with excellent energy return and breathability.
Foamwell’s supercritical foam line covers EVA, TPU/ATPU variants. Specialized equipment ensures consistent quality—30% lighter than traditional EVA, The rebound increase exceeds 25%, and it will not collapse even after long-term use.Suitable for running, basketball and high-performance footwear.
4. Open-Cell Technology Foam: Breathable Comfort Reinvented
Open-cell foam features a connected porous structure that enables continuous air circulation, delivering superior breathability and moisture-wicking performance. It quickly dissipates heat and sweat, keeping feet dry and cool all day, making it ideal for summer footwear, casual shoes and activewear.
Foamwell’s open-cell foam series is optimized for softness and elasticity, with adjustable porosity to meet different comfort needs. Supported by precision foaming technology, our products maintain stable air permeability and resilience, avoiding compression set even after long-term use. We also offer customized open-cell options for enhanced anti-slip and shock-absorbing effects, catering to diverse market demands.
