These are NOT for everyone. In fact, for those who have wide flat feet Driver would hurt you. I've tried expand the sixth toes part a bit but did not work that much. As far as stiffness goes, they are great for backcountry riding and have pretty good traction while hiking uphill. One more thing is that the liner itself is NOT great, so I'd say... ditch them and replace to softer version of Intuition Liners. Overall, for ones with narrow long feet and would love to go off-piste, these are one of the best on the market. But, again NOT for everyone.
