A Fritschi-nél ez az infó: "Can boots with Grip-Walk soles be used for Tecton?
Yes, basically all models with inserts and an adequate retaining edge to hold the boot on the heel are compatible according to the list. Boots with Grip-Walk soles can be used, provided that they satisfy these criteria.
Fritschi recommends in any event to have a trained professional check the compatibility with the 4-point-check."
Én Tecton 12-t használok GW talpú bakanccsal, nincsen probléma vele.
