I've heard good things about these and was considering getting myself a pair. I believe if you buy them off of zappos they give you a year to return them!

I wear inov-8 f-lite 230 and f-lite 195's for the majority of my WOD's. The difference in the numbers is the heel height. If you look at the back of the inov-8 they have arrows right above the heel, 3 arrows: 9mm heel, 2 arrows 6mm heel, 1 arrow 3mm heel, 0 arrows 0 heel. I like the 230's for WOD's that involve high rep/lower weight squatting or Oly lifting... i.e. grace, fran, etc. They are good because they have a slight heel (like my oly shoes) but I can still do other movements if the workout calls for say box jumps or burpees and I can't wear my oly shoes. I like the 195's for WOD's that don't involve lifting but are body weight and running heavy because I have always preferred minimalist running and they are pretty close to the feeling of running in my vibrams... with a little heel if there are body weight squats or something of that nature involved. I wear Oly Shoes for heavy squats, cleans, OHS, snatch, etc... Wearing running shoes (which usually have a pronounced and spongy heel, because a majority of people run with a heel strike and need the extra shock absorbtion) are HORRIBLE for lifting, when doing just a regular back squat with just the bar in running shoes, the path of the bar on the descent can be forward or backward of the center of gravity by as much at 17%!!! Add any sort of load on there and you are looking at a potential injury. I usually go barefoot for deadlift and warm up for squatting barefoot as well, some gyms don't allow it, but it's better for the lift, flexibility and learning to "push through the ground". So are shoes important in crossfit, yes, they are important in any sport you are attempting... you wouldn't wear golf shoes to play baseball right? Overall people in crossfit like inov-8's because they promote midfoot and forefoot strike when running and they have a sturdier heel for less bar movement when lifting. They are pretty decent all around shoes
