I did the same thing...ordered the fabric (non skid) booties vs. the plastic. They sux!! Tried em' for a bit since I had so damn many, but hated them, and got my plastic ones. Here's the thing...no ones removing ALL of the soil...so if they're wearing the fabric ones (or as one guy said above, tells custys socks) NO WAY, even a small amount of dirt (or mildly brown moisture) adheres to fabric covers (or socks) the customers perception could be that you did a shitty job. If I didn't have plastic booties to leave em', I'd tell them to stay off of the carpet for several hours. To me, booties left behind are a must and the fabric ones are a total waste of money for what we need.
