If you're having trouble finding the TF9 inline skates in your size, but really want to try the TF9 boots then you could buy the ice boots and get them converted to inline. I don't know what the pricing is like in the UK, but in North America converting a pair of TF9 ice skates to inline would still be cheaper than buying a top of the line Mission skate. You'd also get to choose the type of chassis and wheels you want if you go that route.
