Feetbelts vs Powergrips vs Chicagowig vs JOL vs Holdfast

slightly off topic but i've been thinking about going clipless but i only have one bike and want to be able to wear normal shoes sometimes so i was wondering if anyone has put feetbelts (or any of the alternatives) on the flat side of a pair of double sided clipless mtb pedals like these ones?

i can't see why there'd be any problem with power grips but if anyone has any experience speak up please!

Potentially your straps could drag on the floor when using the SPD side. Or potentially catch on something.
