The question was:

Got to Biarritz and the airline has lost my luggage, including all the things for my walk. It’s been 2 days and they still don’t know where it is let alone how long it will take to get it to me and the alburge I managed to find is kicking me out on Monday as they’ve run out of room. […] All my advice has been to start anyway, but I need to replace my things. I was wearing my boots but everything else I bought was in the luggage. Could you guys pleaseif there is anywhere between Biarritz to St Jean where I can purchase some gear, rucksack too?
