I use these boots on a daily basis to walk the dog.  Our park is frequently soggy in the morning, and I slip these over big fluffy socks.  My feet stay warm and dry, and I love the little extra nub at the back to help pull them off when I get home.  Over the past five years, I've bought several pairs of "fashionable" rain boots, but they always wind up with a hole somewhere, or the sole separates.  So far, these are a solid choice.  If they develop problems, I'll re-review, but as of now, I couldn't be happier!

It's been a year.  I'm still in love.  No holes, no cracks, no real sign of wear and tear other than they're getting a little dingy (I don't do a thing to keep them clean -- probably a little soap and water would do wonders!).  I still wear them EVERY DAY to walk the pups (we got another since I wrote the first review) -- not just when it rains, but daily because the park is always soggy.  These boots got a little break in the summer, but they sit out in our garage with the leashes, and in Sacramento it gets over 100 degrees, and exponentially hotter in a closed garage.  Didn't hurt the boots at all to sit there all summer, and they were ready to go when fall rolled around. Best rain boots of life!

YOU GUYS!  It's been two years -- still wearing these guys pretty much every day, and they are STILL good as new!!  Winter rainstorms find me slogging through mudpuddles like a champ. I feel like a superhero -- you puny mudpuddles hold NO power over THESE BOOTS!!  They're like a water force field.  They are probably my most solid Amazon purchase to date.  If you're in the market for rain boots, do yourself a favor and choose these ones!!
