In reply to idiotproof (Buxton MC):
Never had any quality issues with my Teva sandals - I've got Terra Fi 4, I think. Very comfortable, but ridiculously heavy!
Also got a pair of Hurricanes I use for messing around on boats, as they're rubbish for walking in - I can feel the strap under my feet.
Really wish Teva would re-issue the Toachi 2, as they are far and away the best sandals I've ever owned, but mine are wearing out
Had a Source pair which were really good until part of the sole fell off - think the glue couldn't take the heat in Egypt.
Otherwise, I had a pair of Merrell that lasted years and currently got a lightweight pair of Blaze Sieve, which are very comfy, but have an annoyingly short ankle strap.
