There seems to be a lot of queries about checking if big feet, bodies, knees etc fit the yak in question. A really simple way of checking is by negative full scale mockups. This assumes that you can judge the implications of the fit:
Using a rectangular pc of cardboard(cheap and quick) or ply(gives a better idea) cut out a pc about 16"x 30". Draw out the form locations that are close to the body part in question but butt the bottom of the form against the bottom of the rectangle and cut out. Place the rectangle on the floor and wriggle your foot inside. Does it fit? If you want a better idea at crimp spots, screw some scrap out horizontally where the big toe is. Maybe put a pce of 1x or 2x on the floor if the bottom really vees up, but usually the heels are pretty close to the ctr.
Works best for the knee form, but the scrap addition really helps for the foot one.
