I walk all day everyday. Typically at least 5-7 miles. I need rubber boots for work and it's very hard to find a pair that is light and comfortable. And also actually has a good tread design.
I just bought some ankle high muck boots that were on sale at Cabelas and in 19 years of spraying they are the best boots I've ever found for work. The only complaint was that I had to put a bandaid on the top of my heel till the boots got a bit broke in and my ankle got used to the new boot. These are the ones I got.

The second best were the Bogs. The ones I got are not on the webbsite. They did last a LONG time. I usually go through 3 pair per year and the Bogs lasted me about half again or twice as long as other boots I have tried. The pair I got were a bit soft soled so it hurt to walk on sharp rocks but overall they were really pretty good. I'm not sure how long the Mucks above will last they are my first pair.
Over the years I've used all types of Waterpfoof hiking boots but the chems I spray destroy them, I've used regular rubber barn boots boot the is no ankle support so they don't work for what I do. I've also used regular shoes with rubber slip ons over them but it's just too heavy.
I love these two outfits, the products are a bit spendy but they really are good.
Hope this helps.
