Savage IslandMen's Black Leather Combat Patrol Work Boots

I just bought this (uk9) but they are, surprisingly, too big. i am a 9 in almost everything, occasionally a 10. is this common?

I have the feeling it should be obvious, but can't see it written down anywhere; are these water proof? As in: stepping in mud/puddles ?

I purchased these boots and have been wearing them for about 3 weeks and the sole of the boot has split on both and they are now leaking water

do they have a steel toe cap?
