VibramMen's El-x Fitness Shoes

Q: I know I'm a size 43 in these shoes - would you recommend getting a 9 or 9.5?

Following a googled conversion chart - I'd go with a 9. My pair fit exactly as expected (I'm a 7 -> brought a 7 -> fit perfectly) and I can wear them with toe socks or without comfortably.A tighter fit is probably better for these shoes than a loose one as they are elasticated slip ons, so long as you don't have unusually long toes!
