In reply to Shiv87:
Good advice so far, while I do not know Cardiff, I have used Up and Under via mail order and Cotswold elsewhere. B0 boots will be fine for Kili. I personally prefer leather to leather/fabric as leather boots are more hard wearing. In my experience the stitching is more likely to go in leather / fabric boots. A tip for Kili, take a nail brush, very useful for cleaning your boots. Choose your boots by what fits your feet best, not the name or model. Buy soon to get them well worn in. Enjoy Kili, if you want more information about Kili, please email me.
