No different in how easily your foot comes in and out over bone stock. Maybe even slightly easier. We didn't put a cleat on the first evacuation hole and that is for safety. The stock footbed has elevated tabs even directly under the bar. The cleats are lower then the old days for that exact reason.
Also note the PRO footbar is actually slightly less trapped then the IQ RAW version and our 2010 Better Boards are perfect on it without any problems. Once again this is the sled that I ride almost every day. 4000 miles on one and 3000 on another. Also keep in mind with over 3000 units in use on this design for 4 years we would know if there was a problem. Probably one of the rarest aspect of Better Boards is the fact that our parts are designed by mtn riders for mtn riders. Not by some design engineer that hasn't hardly straddled a sled. Note that our front evacuation holes are 50% larger then stock. The stock holes are not large enough and a fully encompassed evacuation hole just traps and holds snow. Looks great in the shop works terrible in the real world! The only snow that is going to evacuate on those boards is sugar champagne and we get that snow about once a year if we are super lucky. If the snow is that dry and light it blows right off anyway. With all of this global warming I actually can't remember the last day we had that it was so dry it blew off with zero build up.
By the experience of doing this for years and making over 10,000 sets we know you have to have a certain minimum space or the average type of snow most mtn sledders encounter won't evacuate and you stand on an iceberg (SHOWN IN PHOTO). Now another factor that is going to show up when people get more time on the PRO. In order to clear the stock boards you have to kick it out. Stomping will not do it! Kicking moves the snow right up into the engine compartment along with your clutches! Bad idea and it's going to show up as such in a lot environments of riding. Im going to build a little plastic block off plate 1/2 way up and that combined with my Better Boards will fix that issue.
