power grips?

[NAILTRAIL96]

I tend to shuffle a lot so any kind of restraint is a real pain.

I use PGs since mid-1990s, always prefered them over clips&straps, no need to bend down to get a tight fit, just turn your foot a little more.
And if you ride clipless pedals on other bikes, the move for releasing your feet is very similar, so you use the same emergency reflex.

I like PG's - especially over toe clips, but would always opt for SPDs.

If you don't mind modern and need a good, grippy flat and an SPD - try A530s - I love em.
