You're totally fine.
I have size 13 burton boots on a 159 banana and I never get any toe drag. 25.5 width is enough.
Enjoy the new ride!
Thanks, yeah I took it out today and it was a great ride. I get really good carves out of the board, but I feel like its a little wobbly when I start to gain some straight a way speed, do you ever have the same issues?
