I am Fivefingers' target customer for these -- I love wool and casual styling, plus Fivefingers' toe-spread and barefoot feel -- but I had to return them due to the cut of the heel and poor workmanship.

I've been happy with this style shoes from other makers, but the pair I received cut into my achilles tendon more than can be remedied with mole skin or allowing a callus to form.  I tried not lacing all the way to the top, but that didn't help.  The combination of stiff fabric and a sharply raked shape is a killer.

Another problem with the pair I received is that there's residue on top of the big toe and most places where the fabric meets the outsole.  I realize that with wear the shoes will get cruddy in these locations, but I don't like new shoes to start out that way.

A note about sizing: my experience with Fivefingers is that some styles run shorter or narrower than others and customer comments are a pretty good guide.  Also, Fivefingers has a list of how the styles run relative to each other (e.g., if you wear XX size in style A, then here's what to try in the other sizes).  So I ordered one size larger than usual.  It was dramatically too long for me, and wider than a Fivefingers has ever been.  Love the width and that there's easily room for the thickest wool toe socks available, but the heel top issue is a killer.
