Looking for shoe to alternatibe with Hoka Clifton

Hi, I've been wearing Hoka Cliftons for a few years now, and I'm very happy with them (I wear them with custom inserts). Based on advice of others on this board, I'd like to buy a second pair of good walking shoes to alternate with them, to extend their lifespan and also to have a dry pair to wear after a wet walk.

Should I buy a second pair of the identical shoe? Or is there an advantage to having two slightly different styles? If the latter, I'd love to get recs from Clifton fans for a good second pair.

Thoughts?
