Black Diamond Direct Connect AT Sole Block
Where to Buy
Here's what other sites are saying:
The Black Diamond Direct Connect AT Sole Block attaches easily to the Black Diamond Factor MX 130 and Shiva MX 110 boots, taking them from burly in-bounds chargers to tour-ready speed demons with just a few screws. The Direct Connect is fully compatible with all tech bindings, so you'll be on top before you know it, without spending top dollar on a whole new set of boots.
