Your god Schwalbe is getting into the airless solid tire game for thus adding another big name to the list. Sheldon Brown was wrong. Advancements in foam technology have made airless solid tires a viable alternative for almost all non competitive cyclists/not on the spectrum peoples. Getting a flat is a bitch and most people don't carry around a little fanny pack repair kit. Most people don't want to check their air pressure every time they ride. And flats are a total non starter for commuting. Airless solid tires are best tires.
