Thank you very much for the details. I just recently purchased a pair of UnderArmour running shoes that are made of (I think) a similar foam compound as the Tannus Tires. The logo,label , whatever said something like Lite Speed Foam Technology. Cant remember and cant reference since said label has worn off. They are light , very comfortable and have great traction - on dry concrete or multi surface, but on wet concrete they have horrible traction, like walking on ice. It may be that these are similar materials hence the similar wet concrete performance. On a side note, I purchased these shoes specifically for my commute because of the shape of the soles being conducive to pedaling or so i thought. Any time i dismount onto wet ground, my feet then slip on my pedals necessitating a non skid application to my pedals (until I get new shoes,at least) . I have never had this problem - either wet concrete or wet pedal performance- with any other conventional rubber soled shoe.
