Full of anticipation, I slipped my foot into the first Nunn Bush it's ever been in, but found it very loose on the inside and slipped too easily. I then tested it on the kitchen floor, old linoleum, and found that the fresh sole had almost no friction and glided easily over dry linoleum. They will be sent back and I will look for another set that fits snugly and has less slippage. I usually take 10 but they had plenty of wiggle room and I would consider going down a size if reordering the same brand.
