The overhang on that doesn't look too bad to me. The problem is, it's very hard to tell by pictures. The other problem is that everyone rides different with different angles. The only real way to tell when overhang isn't so obviously too much is to actually strap in and mimic a carve. You can do this by holding onto something. Mimic the carve and see if your toe/heel touches the ground before you even fully engage.
Just for reference, my buddy David Z rode my 157 Proto with his size 11 32 TM 2 boots which are pretty bulky. He had 0 issues on it and he rides everything including lots of park.
Thanks a lot! Already bought the 157, and this kinda reassures me that it was the right decision
