Thanks, again to you all.
I have visited the Star dance shop but they don't have my size. The shop in Bristol likewise does not have my size.
I gave the Burleigh Academy a call last week a lady I spoke to confirmed that they have sizes in stock which may fit me. As such I set off on Saturday to visit them only to end up with a tyre puncture - which cost me £60 to sort out. Hence I did not get further than Pentwyn. On the same day my printer packed up the ghost, after taking a chunk out of my finger. Not a good weekend.
Has this tale a happy ending, I hope so! I have booked Thursday off from work & intend to get to Newport by hook or by crook.
