I can't concur on the Aline (at least for my feet). I was fitted for a set at Precision Ski in Frisco 2 weeks ago, but I found that the metatarsal support was just too much for my feet. I like some met support, but it was just a bit over the top for me. I should also note that I found the material (I guess it's some kind of plastic) to be cold and that's the kiss of death for a skiing footbed.
I also have had numerous custom footbeds done and it's been hit or miss. Believe it or not I've come to the conclusion that there are 2 OTC footbeds that work really well for me - DownUnders and Sole Slim Sport. I use the DownUnders (Ski-Board-Skate Blue) when I want to take up a bit more volume and I like the Sole Slim Sport since it's very low volume (depends on which boot liner I'm using). I really didn't like the Sole Softec Regular that Sole actually recommends for skiing (too high in volume without much support). The Slim Sport model actually provides much better support because it has a support frame built from a stiffer material.
I was planning on doing a big write-up at the end of last season on all the OTC footbeds that I tested, but somewhere along the way I lost interest. Anyhow here's the quickie list of everything I tested and a thought or two on each.
DownUnders Ski-Board/Skate - Blue ($37.00 @alpineer.com, $40 @zappos.com) - nice support, medium volume, great fit
DownUnders Green Cork - ($29.95 @usoutdoorstore.com) - same as above, but a bit stiffer with slightly more support
SOLE Slim Sport footbeds ($32.00 @rei.com) - much stiffer than the Softec Regular model, not posted - but works great in thermo liner
Superfeet REDhot footbeds [size E] ($44.95 @bestinsoles.com) - plastic posting and a medium to high volume, need to upsize to get arch in correct spot
SIDAS Conform'able Volcano Custom Fit [large] ($32.49 @summitonline.com) - very shallow heel cup, very little customization available
Lynco Sport #L425 - posted w/ met support ($48.75 @bestinsoles.com) - not really a great footbed for skiing, but feels great in my shoes
Masterfit Zapz footbeds ($20.99 @summitonline.com, $49.95 @masterfitenterprises.com) - very high volume, very little customization, can't get it into any of my skiboots
SIDAS Conform'able Snow + Flashfit - semi-customizable, low-volume, not posted
ALINE ($69.99) - metatarsal support is a bit too much for me
