C2G Lite Slide Sandals. This neutral Fawn color will go great with summery white clothing since they are almost like a nude against your skin--really pretty and low profile.
There's lots of venting to keep your feet cool and the top strap has velcro for adjusting. I find they run a bit wide and short, but still fit fine. I'm a true 8.5 and need a 9 in these. They're super comfortable, light weight, and would be great for summer travel, being easy to slip off going through security lines at the airport. They're a nice alternative to flip flops and just as easy to kick off in a hurry to jump in the pool or walk barefoot on the beach. Find them HERE.
