Here's the design to date of the wider front wing:

This guy is able bodied, with big legs, 6'2" and has size 14 steel toe shoes with wide soles on, and is sitting with his feet not touching - in fact about a 1.5" gap between them.

Please ignore the bolts, it's a rough prototype - the drawings above are reflective of how it will be when it goes to production.

The way we'll fabricate this will also allow us to make smaller wings too, with smaller footrests, and we're working on parts that will clip onto the front and "cup" people's legs for comfort - sort of like how the arm rests on aero bars on a time trial bike work.
