just googling "club foot brace" seems that there are similar solutions already out there and some look better at first look (not a specialist, so may be missing the point of Wired's excitement). Nothing in all these other braces looks like it costs much (i.e. BOM and manufacturing-wise). With regard to price to end-user, especially in US, - it doesn't matter whether your device costs $20 or $200 - it will be sold for the same $700, and thus expandable braces may be more cost effective because they minimize the occurrence of that $700 charge. Though, again, i'm not a specialist and may be really wrong - the guys most probably did improve the situation, just hard to see it behind the hype.
