I was looking at these or next year's UNION Forces and I really would like canted footbeds, but I wasnt sure how much stiffer the UNION factory binding is compared to the Forces?
I'm going to guess the flex is the same. Next years Force baseplates have the same contact profile and nylon density as the Atlas. They're essentially the same baseplate with a different footbed.
The highback on next year's Force is the same highback as this, but with the traditional Force cut outs, which are entirely for design. I'd say the Force highback flex will be identical to the Team highback.
The new Force ankle strap appears to be a symmetric version of the Atlas ankle strap so I would assume the construction is the same and therefore the response is the same.
Of course, these are all assumptions based on what I see from photo's.
