I started off with hire boots and to be honest it was the smell of a thousand pairs of sweaty feet that encouraged me to buy my own which I did in Borovets (these were an improvement on the hire boots in all ways).
I think next time, I will buy in the UK at a shop where they are prepared to spend an hour or so getting the fit just right (the shop in question didn't do the 'moulding' thing that I have heard you can do)
I bought mine in the UK, never looked back , soooo much better to have your own so get the credit card out and take the plunge
then at least you wont have to put up with the smell of a thousand swetty feet again.
