As promised, here's my first impressions. I ordered the head stratus pro's. They arrived today . To make sure they fit alright, I put them on for about an hour while around the house so that I didn't violate the bomberonline return policy. Here's my first take on their fit. For this discussion, I currently own a pair of about 10 year old raichle race boots that I had back when I was racing DH. They're fit (footbeds, etc). I normally ski in the blue lange's (Race boot) from about 5 years ago - just to give you a baseline comparison.
Now... the Heads are a heck of a lot more comfortable than my raichles. As mentioned at the beginning of the thread, the raichles absolutely crush my arches. As a result, I will stay miles away from the Deeluxe boots. Also, to understand the fit, I find I have high arches, a medium toe box and a narrow heel box. I'm finding the heads have a medium toe box, ample room in the arches and a medium heel box - reminds me of when I tried on the Nordica race boot a few years ago.
Also, the cuff on the heads is lower, so although I don't have gi-normous calves, they'd fit those who do. By the same token, I'm not finding my calves are swimming with room, so they're not overly spacious.
Suffice to say, I'm psyched. I now have a true pair of snowboard boots and will stop cringing in pain at the thought of squeezing my feet into the raichles.
I anticipate busting them out this weekend, so will update the thread on my thoughts.
Edited to add: The above is with the stock liners, no work done, no custom liners, etc.
