If you can do a track stand and can ride very slowly without falling off, then you are good enough to ride clipless.
Road racing shoes are un-walkable. MTB, leisure and touring shoes have a recessed cleat and a bit of heel. Some are good for a few mins of walking others can be used for all day hiking.
Unless you race, a more practical shoe may be better.
Race pedals have a clip on one saide to save weight. You can fit double sided MTB pedals, which is what tourists often do.
