In reply to becauseitsthere:
I think most of the shoe companies release around march/april time.
There is a slight design change on the Solution (I believe it is just color wise tho). Evolv release the Nexxo (slipper with a velro strap) Axiom (all day lace up) Elektra Teal + Elektra Violet (Elektra shoe but in two new colors) Defy gets a 'redesign' (looks like a different color tongue and edging color around the fabric)
Havent seen anything from other shoe companies
