I needed some shoes that I could slip on easily to run outside to perform some chores, or that I could wear all day if I needed to.  These fit the bill.  They're very easy to slip on / off, yet, when they're on, I don't feel any slippage at all.  I used to wear an old pair of loafers when I needed to do some light work outside, get the mail, feed the animals, etc.  However, they were low and were not suitable for wet or cold weather.  These keep out the water, and are high enough, and fit snugly enough, that there should be no issue with snow and ice.
