I play only on Har-tru and need a clay court specific tennis shoe. I own a pair of Adidas feathers from 3 years ago with an outer sole that has dimples designed to grip a clay surface. Back then, the feathers were one of the few options for clay/Har-tru players. Now I see Adidas and Babolat offer clay shoes with a herringbone outer sole design. I'm leaning towards the Adidas Barricade 7.0 Clay shoes, but thought I would get some feedback first. Can anyone weigh in on the current selection of clay shoes? I have fairly narrow feet, which is why I previously chose the feathers. Does the herringbone outer soul really provide better traction on clay/Har-tru? And why is it more shoe companies do not offer clay specific shoes? Aren't they ignoring a large and profitable segment of the tennis public? Thanks.
