Hey Chef, I get up w/ one foot in. My concern was wanting to match the thickness of the footbed cushions on both the boot and the TP. I first tried the original radar ARTP or "slipper" as it has been called here. I knew I didn't like it immediately after a dry fit...never even mounted it...I just returned it. The newer one has a floating tongue w/ an adjustable bungee strap over it. I set the bungee tension to my foot size and forget about it.  After getting up, (as I did w/ my HO TP) I softly kick my foot in, then "creap" it forward by scrunching/walking my toes foward. The footbed is step-grooved so the toes grip it easily. I like how the bungee flexes, then recoils allowing me to get my foot in as deep as I want, but maintain the desired strap tension. I should say that where I normally ski, length of lake is not an issue, so I have plenty of time to get the rear foot good and planted inthere. I don't have my ski handy at the moment to verify this statement, but I believe it (the overlay) uses the more modern material (like the radar boots, that don't need slime). Thus, it is less sticky then rubber when inserting your foot. If interested, I'd be glad to take some close up pix when I get home to send you.
