I bought mine in evo.com (not sure where ur at). I tried the districts first, bought them, went out for a few times and I didn't like them they were too soft, so thankfully they literately starting falling apart after the few times, liner was messed up, stitching started to get undone, etc... so I called EVO.com and they were awesome to deal with warranty, the sent me a new pair, but I upgraded the order to the 2012 KAIs, and I absolutely love them, nice and rigid, I feel as I have more control, feels more direct, IMO. I'm a noob to boots, not sure of that's the case, but feels that way. One of the inside liners is already messing up on my KAIs, about an 3 inches up from the heal, but honestly not sure if its a Ronix quality thing or the way I've been putting them on.
I've got a hook up with LF products, so I'm gona try the vantage next time, or whatever their most rigid boot is.
I tried some cheapy LF ones, and slingshot, can't remember either model, but after trying the Ronix are by far the most comfortable though. IMO.
