I prefer Rykas, when they fit. I've had size issues lately with them. But I've found the Go Walks have no support. I tried 2 pairs. One caused a blister because of a flaw in the padding. The other was better, but after walking half an hour my feet were tired and hot.
Personally, the Best shoes I've found for summer travel are the Clarks and Ryka fisherman sandals. I have somewhat narrow feet and I'm over 60.
