I bring 3 types- leather Rockport sandals, Sperry Dockers and a good pair of sneakers made for walking. My DW thinks I’m crazy since she can last all day with the cheapest pair of flip flops or sandals on the market.
I find that unless I am going to be on my feet all day sandals or Dockers are A-OK. I’ll wear sandals if it is not going to be a wet day (short bursts of rain ok). If it looks like lots of rain Dockers are the daily choice. If we are going to be away from the unit all day I want the extra support of a walking sneaker.
Having more than 1 pair also allows your to air out your shoes. This is important. The last thing you want to do is put on wet shoes from the day before.
