Solum develops a plant-based additive that replaces petrochemical inputs in rubber and plastic shoe outsoles. It is made from agricultural waste and is sold to footwear makers as a processing aid rather than a finished shoe. Its R&D is in Montana, with compounding in Vietnam and Guatemala.
Sells the outsole material technology itself, designed to work in existing rubber and plastic production without re-tooling and to reduce microplastic shedding.
