Here's what other sites are saying:
Want to get out and tour on the new Kingpin but you have an AT boot that doesn't have the standard "ledge" at the heel - like a Dynafit TLT 5 or TLT 6, or Scarpa Alien? You'll need these heel adapters. The Kingpin's heelpiece is DIN certified and has side release capabilities. Because the heel piece works more like a standard alpine binding, you don't need a boot with tech fittings at the heels, but the ledge at the heel needs to be the standard ski boot shape. If you're not sure, give us a call. Boots with DIN ISO Norm 9465 will not need this adapter.
