I want these and I am usually a big size 7. I bought a pair of sketchers ballerina's size 7 a while ago and they fit perfectly but of course the boots would be worn with socks. The 8's in the boots are out of stock - do I risk ordering the 7's and hassle of returning which makes me grind me teeth? Is it a fairly safe bet do you think? Because I cancelled the uggs order so I need boots.
