My heels keep cracking and I'm fairly sure that being barefoot on our hard tiled floor isn't helping so I'm looking for something to wear inside as lightweight slippers. I've tried my Havaianas but they are too plasticky, my Birkies are too heavyweight and my Saltwaters are too substantial. I don't really want anything warm so Ugg style flip flops are a no no but can anyone suggest anything lightweight and open (rather than a closed slipper) but with a bit of comfort to it which might do the trick?
