Thanks Diana! I've actually done that with the Ebay search, but all the ones floating around are either not real leather or have the wrong width. I think chances are slim to find a replacement this way. My Birks are now dry and unfortunately the smell is back. I'm not even sure what this is, I haven't smelled anything like it before. I think I'm going to buy the Birks from the first post. Still a bit undecided, but if I wait too long someone else might snap them up...
Thanks Laurel! Keen isn't as common here, so what I've seen in stores and online is always still fairly expensive. I don't think I want to spend so much money on shoes I probably won't be wearing again afterwards.
Thanks Adela. I did have a pair of Tevas around ten years ago but I never wore them much. Also bought for a holiday (Norway). I agree that some of the Tevas available right now are relatively pretty, in comparison with other trekking sandals.
