I must admit that Zipfits came very expencive, but super good for my feet.
Expencive due after 4 very happy years with Palaus on my UPZs i realized that with Zipfit i can go one size smaller boot. Never had issue with Palaus anyway, just felt that some times had heel lift
When you go to custom, you either need to know what to ask, or get recommendations from manufacturer.
I started with later one with Coiler, and then later was able to go with former one, but with great help from Bruce.
Sewing broke for me too, fixed it and broke again.
Then i bought this one, no issues since that, and it is muuuuch better

Crazy Banana "Mad Max" with steel edges and Emery bindings with Koflach boots.
Next big step was Coiler NSR and final step plates, now more than 500 days on plate riding.
On Allflex/Vistflex type plates it is not so big issue as on old style plates where long stance force your bindings to incorrect place regards axles.
Dont have axles due i use now Allflex inserts Best.
Darn, that is painfull stance with plates. I have huge issues even my 54cm stance,
Luckily i'm 180 so i can survive with 54, i use 55 some times but due moving stance front and back 1-2 cm based on slope condition it is on limit with plate designs / available inserts.
