Yes they had on our news not too long ago that barefoot was best.. and flip flops that follow the natural form of your feet... I wear flip flops in my kitchen because it is vinyl on concrete and I get shin splints... The rest of the house I put in this type of wood floors that has a layer of cushion underneath... because having a house on a concrete slab... is very bad for your feet, legs, back.. everything..
I will never buy a house on a slab again!!!
