AJ 1 mids will likely feel like a "cheaper" dunk to skate in but they can totally work. I'd say go TTS and swap or place an insole of choice in on top and get to skating!
The cheapest I've occasionally found them is around $80-100 when they normally go for $110+ but it depends on your local stores or if you're looking online.
Sheik, Shoe Palace, some Footlockers, Eastbay (webstore), and Jumpman (23) stores should have some in stock.
