Why are accessories like the NTT not made from recycled material?Updated a year ago

Mainly because there is no commercial approved alternative to EVA yet. Supplements, such as Bloom®, an algae product, will influence shrinkage and production time of each part, which will have great impact to process cycles and price of the final product. We are doing what we can do now: Buckles and Heel Cushions as spare parts, packaging using recycled material, sourcing new material for long term test and exchange bit by bit without losing performance.
