I like my neoprene overshoes bu I think the problem for me is that as my biblongs get tucked inside the top of the overshoe, that’s how water gets in.
So overshoes are great at keeping out splashes etc but it’s where they wrap round your shin/calf that lets in the gradual drip, and if you’ve taped up the holes in the bottom of the shoe then you are just going to get a puddle in your shoes!
So I would suggest just embracing it. But if you want to try this…leave a few holes open on your shoes so that water has a way of getting out, if this is partially hidden by overshoe then great, and trying to seal, as best you can, the join between the top of the overshoe and your leg. Maybe wearing the biblongs over the over shoe? Although that may have fashion repercussions
