> Pop down to a local shop and try a few on, every shoe has a different fit so you need to test them out. Once you know what brands/size are a good fit you can always order online or buy second hand.
And what do you do in a few years time when all the retailers who stock shoes are closed down, because everyone else did exactly the same thing? If you can't get to a shop to try them, then fair enough, buy online, but if you can get to your local independent retailer to try them on, buy them there. Don't waste their time and then buy them for £5 less from someone who's selling out of their back bedroom. Not to mention the fact that the best manufacturers of climbing shoes still make their shoes by hand, so there are always slight differences in the sizing from one shoe to another.
