In reply to Duncan Beard:
Officislly those have so called touring soles. Which means that either you need specific touring bindings, or modern Multi-Norm bindings (e.g. Solly Warden).
That being said, a lot of folks have used older style Solly S9xx (I guess it’s the STH series these days) where you can adjust the height of the toe piece. Also Marker’s Royal binding family seems to cope with the situation. Albeit you need to understand that using non-official combos the release pattern might not be correct (either they come off too easily, or don’t… both will be a problem).
