I purchased these NB MX20 Minimus shoes as an alternative to platform weight lifting shoes.  I like that I can transition from lifting to sprinting without requiring a shoe change.  Being flat bottomed, these shoes allow you to more easily achieve proper weight lifting form by not elevating your heel.

My only complaints are that the toe box feels narrow for a "Wide" shoe and that the laces feel cheap, with a tendency to cut into the top part of your foot if you attempt to tie them too tightly.  This is my first minimalist shoe, however, so I expected there to be some learning curve associated with transitioning away from traditional cross-trainers.
