I own speedgoats and they are great shoes but definitely not waterproof. I have also tried a few different waterproof type socks and whilst maybe they keep the water out they are usually so hot and sweaty as a bi product that your feet get wet because of sweet instead and it feels equally terrible.
I just learnt to embrace the wet feet and kind of learnt to enjoy it. Just plow through puddles, get your shit utterly drenched and you stop caring.
One of my favourite runs of all time was during torrential down pours where I ended up wading through knee high water. It was fucking great :D
