i thought that the raised platform on many of the double-up shapes and now the Murray was to create a canted platform to improve the riders stance. Wasn't/ isn't the argument that as the distance between your legs increases it traces the path of an arc... the picture Leo Da vinci made comes to mind with the man and the outstretched arms and legs
Obrien introduced canted footbeds (with "power arches") back in 2011I think, and then LF copied them (read: sharing tech within motion watersports) and introduced canted beds a year later, hyping them up to be the latest and greatest. Too bad O'brien kinda takes a back seat to LF like that sometimes... but i am getting off topic.
Very kool tinkering with the boots. i have done some mods to my boots in the past (footbed inserts, adding straps, using neo sock inserts). it is fun to play around with that stuff.
