In reply to david100:
I have a pair of Teva approach shoes, lined with Event, that I think may be leaking after very little wear. I say "think" because I found this out after misjudging the tide on a beach earlier in the week, and am not 100% sure that the sea did not go over the top.
However, to be honest, I only use them for kicking about in, they are super-comfy, stylish even, and only cost £30 from TK Maxx.
