I’m a runner, and will definitely bring a pair of sneakers- favorites are by Mizuno (just bought a new pair of Wave Runner 22s- no break in time needed, love them!). I don’t like wearing sneakers in the parks all day though, my feet get hot and tired- especially in the hot summer. So, I am also bringing a pair or two of Toms. They are so light, and I appreciate having my foot covered. No stubs, scratches, stings, etc. I will bring one of the two pair of my 10 + year old Old Navy flip flops (they have a shape and coating that they no longer produce). I have other flip flops, but these two are perfected conformed to my feet, and obviously have stood up to the test of time. Also, a pair of Keen sandals, golf shoes, and probably will throw something else in the bag right before we leave. A girl likes to have choices.
