The Anatomy of Footwear Cushioning
Many layers contribute to overall footwear comfort, and we’re taking apart a shoe to go inside each layer and how it helps with everything from cushioning to rebound.

Is a petroleum-free future finally on the horizon for polyurethanes in footwear?
Be the first to discover as INSITE Director of Innovation Caleb Dyer speaks at the 2024 AMI Polymers in Footwear conference on Tuesday, July 23rd, 2:40pm PT in Portland, Oregon.
Caleb will talk about the road to 100% bio-based PUs for footwear, using INSITE Levation poured PU foams as a case study in how various plant-based feedstocks can boost durability, performance, and sustainability.
INSITE will also introduce the latest foam innovations that are helping us inch closer to petroleum-free chemistry for footwear PUs.
