My kids are one sock kids – they just love walking around with one sock on and one sock off and I can see it – it is like a cooling device or cooling system that they have – it is like when you sleep with one foot in the covers and the other foot out of the covers I suppose and I do that sometimes all year round actually. But it is funny seeing my kids just walk around with one sock on – and other people find it a little strange too when they come in the house
