Mephisto Women's Lace Up Cool-Air (Shock Absorber) Shoes, 8.5US, 6EUR, UK6? Purchased several years ago. Worn only twice.  Too big - they have been in wardrobe since. It would appear Mephisto 8.5 US equates to UK6.  Several Mephisto  listed at this size give UK6.   Again, please check before buying. The side internal sticky  label still attached,  could be removed - but shows leather content, so  have left it.  There are a few little external marks from when worn but have uploaded  last four photos which had another  leather balm polish.  They look brand new inside, external leather still basically  excellent  - apart from tiny marks shown.  If you are unsure of size please check since I do not refund.  Mephisto site show size conversion,  they are super brand. Could be made in France, but cannot find origin of manufacture. Probably  on box which was discarded.
