The shoe with velcro is below. BASE. It has a velcro X strap where the medial side is fixed and the lateral side is adjust, with self centering tension thanks to central nylon D-ring.
The outsole design goes from recessed to raised tread in key sections to provide different kind of traction as well as wear (shoe is designed for forefoot/midfoot strike so the focus is on the forefoot). Outsole BTW is also curved in section profile in forefoot and heel to mimic the foot and is even concave under the ball of the foot.
The 1pc midsole /outsole, are you talking about the new SS13 model with IBR?
The two different type of eyestay on the leather shoe was not needed for asymmetrical construction but provides a different sort of lock down and aesthetic.
Happy to answer any questions.
