If the plan is to be able to ride flats, and maybe transition to clips in the future, I would go with something with a flatter sole than the Explore. Lots of brands have a shoe with essentially a flat sole, that has a removable cleat filler, that can be taken out and replaced with a recessed cleat.

The sole on the Explore just looks like it’ll be wobbling around on a true flat pedal. For flats, you really want a shoe that has an almost skateboard-shoe look.
