OK, I pretty much only buy MBT shoes for the past few years, despite the fact that the soles are only good for about a year, before they need to be replaced.  I'm a fan of the company.  And this is an attractive, semi-formal shoe, good for work or parties.  I like the convex, rolling sole that prevents me from slamming flat-footedly onto the pavement, exacerbating an old knee injury.  Be that as it may, after wearing these, I strained my achilles tendon.  It doesn't seem to support the back of the foot as well as other MBT shoes.  This may be the fault of the dress laces, which a slim and waxed, and may not hold a shoelace knot as well as the thicker laces.
