http://www.justtogs.co.uk/products/index.php?c=18I LOVE MY MUCK BOOTS!!!!!!!!!!!!!!!
Well technically mine aren't actually Muck Boots but the Just Togs cheaper versions but the same thing really. I have the 'normal' ones which admittedly they are very slippy but the most comfortable thing ever!! I wear them for hours everyday, walk miles in them and paddle in the sea most days!! This pair have lasted me 3 years so far and have only just started to let water in.
I've replaced them with the riding version, these have much better grip BUT they are alot tighter on the leg and have taken a few wears to get them comfortable but yesterday I had them on all day for 2 dog walks and 4 hours of riding and my feet were extreamly toasty and not at all achey!! They are harder to get on and off but lovely to ride in and wear around the yard. I highly recommend them.
