When it comes to high performance shoes, there is very few left. Dynothane/3G is almost non existent. Dexter buts out one new crappy color every year. Etonic is gone, although it looks like they are making shoes for Brunswick, now. Linds hasn't made a new shoe since the 80's but still charges a premium price for glamourized house shoes.
They can but out 10 new balls every week, but shoes............Nope.
