Benefits of EVA Foam
Compared to the cheaper PE foam alternative, EVA foam is a far more superior material in terms of protection and durability.

PE foam is lighter and doesn't offer as much impact absorption. If you press into PE foam vs EVA foam, you will definitely see and feel the difference.
The lightness of the PE material also means it will deteriorate faster with each wash and wear cycle, meaning you will need to replace it more frequently in the long term.
