Yes, if you plan to use tech (pin-style) touring bindings, you need boots with a tech touring sole. These soles have built-in fittings that lock directly into pin bindings, which are the standard for backcountry skiing because they're lighter and allow a natural walking stride on the uphill.
The big thing to watch out for: tech touring soles are NOT compatible with standard alpine bindings you'd find at a resort. If you want to use your boots at the resort too, look for hybrid designs that combine tech fittings with a GripWalk sole profile. These give you pin-binding compatibility for the backcountry and work with GripWalk-certified alpine bindings for resort days.
Just remember that even hybrid boots need to be paired with the right bindings on both setups—always check for the GW symbol on your alpine bindings and verify your tech bindings accept your boot's specific toe and heel fittings.
