I went to their "open house" and unfortunately couldn't get anything suitable in my size. Not to be deterred, I still ended up with a pair of Altra Provision for the kid.
This is a pair of zero drop shoes. Something not entirely new to the kid who wears a pair of racer for running.
From its website
Modeled after The Instinct™ platform, The Provision™ adds a firmer midsole and a removable varus stability wedge to assist men with fallen arches, excessive overpronation and knock knees. Built for moderate and high overpronation, the Zero Drop™ platform, foot-shaped design and stability wedge combine to provide a high level of stability without the excessive bulk and weight of traditional stability shoes. Simply remove the stability wedge to convert this shoe to work for neutral and mild overpronation.
The included Stability Wedge™ provides a moderate to high level of stability and is optional. It is designed to provide additional support to those with excessive pronation or flat feet. It addresses the four main challenges with stability in running shoes.
The stability Wedge is the grey color insole like object at the bottom of the picture. The blue color piece is the insole. Both are removable and washable.
