I live in a snowy state which has FIVE official seasons, one of which is called "Mud" (it precedes "Spring").  Moreover, even in bona fide Summer, our Farmers' Market is on the town green, which means that, if it's rainy, the vendors' awnings drip down to create...mud; or even if it rained the day before, there's...mud....underneath.  One day I was at the FM with a friend of a friend, and, while my sneakers were being covered with mud,  she was wearing these!  I amazoned, found them, was thrilled to discover they come in a rainbow of colors, ordered them in blue, and I've been wearing them all Spring, Summer, and Fall ever since.  They run very true to size, and so mine are roomy enough to accommodate slightly heavier socks in Spring and Fall, and light socks in Summer.  They're rubber, so when they acquire a mud mustache, it's very easy to run them under the faucet or wipe with a damp cloth to look as good as new.  I'm writing this after two full seasons of wearing them almost daily, and they should be good for many years to go.
