Cost a little more than the shoes I usually buy but worth it.  I prefer walking to driving or taking the bus and walk many miles daily.  $30 shoes wear out in a matter of months.  These last years though, and really are waterproof.  They have pretty good grip too, but still need to be really careful on ice.  I discovered them when I found them at a thrift store for just a couple of dollars.  Even though the thrift-store pair was already well worn, it lasted over a year and since I couldn't find it again in a thrift store, decided a new pair would definitely be worth the price.  I think it's been about a year now, and they're still my favorite.  If you wear your shoes all day and are active, this shoe is best worn with thick absorbent socks though because no water in means no sweat out either.
