Update: The boots are less than one year old and have dry-rotted and cracked already, plus the lining is separating from the rubber shell.  These are no better than the cheap ones I bought the first time.  DO NOT buy, unless you just want them for 10 months or so. They have been used about ten times and sit in my workshop in a household environment.  NOT GOOD quality at all.

My previous Boss over-boots (looked just like these CLC Slush boots) literally dry rotted. I wear size 13 shoes and wanted boots to fit over my shoes so I bought size 15 CLC Slush boots. These are a bit big so the loafer shoes I am using inside the boots have heels that slop around.  I have not tried the boots with larger work shoes or good sneakers, but the size 15 CLC Slush boots are good quality and I hope they last a long time. I only use them on occassions so I can't comment on heavy use wear.
