I've had Sofft sandals in the past that I adored. Don't own the ones that Murph links to, but wish I did!!
This summer, my most comfortable sandals have been the EF sport and my Fitflops. Opposite to bj1111, I wasn't able to wear the Ecco Damara because it didn't offer enough arch support for me. I bought it for travel but was disappointed after putting it (literally) through its paces. (BTW, I have narrow heels, and a medium forefoot, medium volume foot overall, high arches/ instep but not fleshy). Normally, Eccos are great for me, and I have the same sneakers you link, but the Damara style was just a bit "off" for my foot, while the EF (though pricier, alas!) seems to work.
ETA, the only reason these Fitflops work for me is they are adjustable. I have to adjust the tops to make them snug enough. The ones that don't have buckles do not work for me.
