I used to have Five Tens, and then I went on to the Bontrager Flatline; and I guess I have to say that the Flatline is a lot stiffer. They are a lot more solid AND just as grippy, but for me it was a better switch to the Flatline .. ... away from the Five Ten. Not that the Five Ten was a bad shoe! it was a good shoe! I just feel a lot more confident in the Flatline from Bontrager. And wow! Bontrager gave me a 30 day warranty for fit

Truth is though... after umpteen years using cleats; I decided to go back to cleats just about a month ago. But if I were to go back to flat I would use and highly recommend that FLATLINE!!!
