Which is a better sole material, EVA or rubber?
EVA material proves to be better than rubber as they are one of the best shock absorption materials available today. Thus, most of the prominent brand joggers use this in shoe soles to get a good combination of shock absorption and lightweight.
Features & Benefits of EVA sole that make it better than rubber:
This material is highly water and corrosion resistant.
It offers ease of processing (cutting, gluing, pressing and laminating).
EVA sole is anti-vibrant (good tensile strength & shock cushioning with high toughness)
They provide insulation towards cold temperature
Closed foam sound insulation quality.
EVA materials are being commonly used for the middle sole of shoe parts, outsole & insole of sports shoes and also as soles for slippers and flip-flop.
EVA has a lower thermal conductivity than rubber so if you’re spending extended periods of time outside in the winter (standing on ice or concrete) - your feet will stay much warmer in EVA boots when compared to similarly constructed rubber or rubber soled boots. Also, EVA tends to be much lighter allowing the manufacturer to put extra thickness in the sole without increasing weight which also increases it’s insulating ability. I’m in my second winter using NAT’s EVA winter boots and I’ll never go back to traditional pac boots or rubber ones.
