I had the Dynoroos Sport Ultra and used them for 3 years.  Very comfortable, decent price, and very stylish.  Adjustable soles and heels.  The inside lining was coming apart a little, so I decided to get a new pair of shoes and attempt to fix the lining of my old shoes and use those as a back-up.  I fixed them, and picked up a pair of 900G Tour Ultras. The Tours are a bit more expensive, but even more comfortable,  more stylish (IMHO), and comes with extra goodies like shoe keepers (or what ever you call those plastic things you put in the shoes to keep its shape) ,shoe bag, and an array of soles and heels.  

I actually passed on my fixed Sports to my 13 year old son, who seems to be going through shoes every 6 months!  The timing was perfect as he was on his 5th pair of shoes in 4 years and now my shoes fit him a little loose (so he will grow into them and maybe only 1 size too big for him) but he loves the Sports as well.

I highly recommend the 900G's!

i wore dexters for years and finally gave up on them after not being able to find just the right slide and pathetic customer service. since then i've had two pairs of dynorooz sport elite cabretta's, a pair of dynorooz tour ultra's, and two pairs of 3g tour ultra's. 3g tour ultra's are by far the best bowling shoe money can buy. quality materials and top notch construction. great customer service. and six(6)soles and six(6) heels to custom-tailor your slide. i won't buy another other brand. i wouldn't wear dexters if someone gave me a pair.
