Treair is a brand of British-made footwear made by the White & Co. shoe company in Northamptonshire. The company, established in 1880, originally made sports footwear such as cricketing shoes, until it was commissioned (along with other manufacturers) to produce Dr. Martens boots. At that time, the air-cushioned sole used felt to provide cushion, but when the company developed a foam filling, it branched off and produced its own boots and shoes branded as Tredair.
