The walk mode on these was designed wrong. Save your money for a different boot. And SCARPA customer support, while able to send some spare parts, was very slow and unable to actually fix this issue: https://www.youtube.com/shorts/6qdoGSHhrxk

Thanks, I will check back then.

Will the new walk mode lever be backwards compatible with the Maestrale RS 4? Mine are non-functional

I would not recommend these for Scarpa F1 GT (or XT). I tried replacing the stock liners but the thinness of these Palau liners leads to very nasty pressure points on the lateral side of the instep buckle on both of my feet. The stock liner has a thick foam pad on the instep and tongue that mitigates this. The Palau liner also feels much thinner and less substantial.

Let us know when you get the BSL chart!
