Family member had a pair of Dexter The 9's. After less than 2 years, the bottom on both shoes had cracked all the way through in the grooves where the removable soles set in to. Contacted Dexter, and they literally responded with "our high performance shoes are not designed to be durable." They offered to sell a replacement pair to us "at cost".
Needless to say, those were replaced with a pair of Brunswick Team Brunswick shoes and so far so good.
I use the Dexter SST6 LZ and they have been fine. I personally would buy Dexter shoes again, but would avoid any variation of The 9's. The 3G Tour Ultra shoes are also supposed to be amazing.
Another family member uses the Hammer Boss shoes and is happy, aside from the universal push away sole on the non-slide foot needing to be replaced after 3-4 months because the velcro got fatigued and stopped attaching to the shoe.
