I have a pair of xxxtra's and have owned a pair of kid-pro ams from dynothane for 5 months. Let me tell you, the comfort difference is phenominal. The leather is very soft and light, and the padding for the sole is very comfortable and thick. They are the most comfortable shoes i own, and also offer more support than the xxxtras.
The soles and heals have held up well for me, although i've heard that the dotted heals do not hold up well at all. I didnt like my xxxtras because they were uncomfortable and the waffle inserts wore down too fast. I do not have to change heals often, but when i do, the dyno's offer a little more versatility as there is more surface area available to change.
The one thing nice that i always liked about the xxxtras is that they slid a lot. Dynothanes do not slide as much, unless you get the felt sole and red leather heel. I used a red leather heel from dexters when i first got the dynothanes (cut a hole in it) and it slid too much, and i have since converted to the flat light grey heal and number 5 sole. It took a while to break in these two, but once i did, it slid a lot more then when i first got the shoes. STill doesnt slide as much as my linds(i'm not using the lowest sole or heal obviously), but i now have adjusted my game a little bit and just don't slide as much.
