If you run a hose over the toes of the shoe, your feet won't get wet.  However, if the water seeps down from your pants onto your socks into your shoes, then your feet will be soaked.  The shoe doesn't form a seal around your foot.  It doesn't state that it does, but I just wanted to be clear about what "stop the water penetrating the shoes" actually means.

The shoe is tighter than a regular shoe, particularly around the front of the foot, but this is not a deal-breaker in my mind, as I got used to it pretty quick.  Well, tighter isn't really a good word, as it's not compressing the feet, but it's more rigid, like it won't expand.  It's just if you're used to your running shoes feeling a certain way, this feels different.

The greenish shoe is $50 less than the reddish shoe, so that warrants my 5 stars.  If I had to pay the $130 price for the reddish shoe, I wouldn't rate it as high.
