SPARXmens SF0014G Blackred Flip-flop - 10 UK (SF0014GBKRD0010)

Can I get it replaced for size variation? I don't see any replacement policy!

Is this slipper to be used at home only or it can be used for outdoor? Can it used in rainy days outside?

is it slippery on wet floor as well as polished surfaces(like super clean tiles, marbles)?

size chart not given?
