From Amazon answered Qs:
Question: Anyone can compare the venture 5 to the venture 6? any real difference? thanks
Answer: TL;DR: GEL Venture 6 > GEL Venture 5 (previous FP)
I feel more foot support. There is a difference.

They seem to be better structure/build quality. They are more supportive, and the bottom of the soles didn't start to come off like with my 5's. I would say if you are looking for an upgrade from a 5, this is great.

I prefer the 6. It's softer, the fit is better (half-size down though) and there is greater midfoot stability. The 6 seems like a better-designed shoe all around.

i have tried them both on, on the 5 the bottom section of where the laces are stitched (top of the toe box) circles down toward your toes and affects how the shoe bends, it digs into the top of your toes a little, the 6 is flat across and does not do it, much better, look at both pics from top to see
