Lake Shoes 2021 tighter heel?

I have Lake - CX 241 wide, the best comfort in the forefoot, but the hill slippage is awful even after molding it. On the long rides it really started to stress my fascia plantaris.

The new 2021 version of road Lakes they claim: “. The main differences include increased toe pitch & heel lift, a tighter heel & a slightly wider ball girth to allow the foot to expand under high pedaling pressures.”

Did anyone have the experience with a new model and how does it compare in the heel part?
