Why You Don’t Want to Use Your Ankles to Absorb Shock on Your Mountain Bike.

In this episode of the BikeJames Podcast I tell you why trying to use your ankles to absorb shock on your bike is a bad idea and actually makes it harder for your lower body to absorb shock properly. The notes for it also turned into an article, which you can read below if that works better for you... One of my biggest surprises with bringing the Catalyst Pedal and the mid-foot position it allowed to the MTB world was the push back I got from the skills training industry. It turns out that the vast majority of skills coaches and organizations have bought into the false logic of needing the be on the ball of the foot to move properly on the bike. The logic goes that you need your ankles to help absorb shock and that if you use the mid-foot position then it is like landing a vertical jump with flat feet, which is very jarring and obviously not the way to land a jump. The idea is that the range of motion of the ankle that is giving you the extra shock absorption that is making the difference in the two landings, which means that you need your ankles to absorb shock. The problem is that, once again, people are pointing to analogies from other sports/ activities that don’t reflect the context of being athletic on the bike, i.e. the feet don’t come off the pedals. When your feet come off the ground then you do need to use the ankles to help you land but even then they aren’t being used to absorb shock. In fact, MTB is the only sport where coaches are actively looking to put extra stress on the ankle joint. It is known as one of the most sensitive and easily injured joints in the body and the goal is usually to minimize stress in order to avoid injuries. The ankle joint is a small joint with a long lever arm, which magnifies stress being placed away from the ankle joint itself. It is not designed to absorb shock, it is designed to move itself (and the foot) into a neutral position to let the real shock absorbers do their work. The hips are surrounded by the largest muscles in the body and have amazing leverage for both producing and absorbing shock. They are the shock absorbers of the lower body. Most lower body movement problems stem from not being able to use the hips properly, which makes using them efficiently a top priority. But your foot has to be in a certain position and stabilized correctly to let the hips do their work in the most efficient way possible. If it isn’t then the hips can’t absorb as much shock, which places that stress on the knees and ankles. This means that being on the ball of the foot screws you in two ways… First, having the pressure point being so far away from the ankle joint increases the leverage and hence the force being placed on the ankle joint. This is why you’ll see people’s ankles buckle sometimes and in extreme cases Achilles tendon tears (ala Rachel Atherton a couple years back). This is why most DH riders actually run a more mid-foot position than you are led to believe. Second, by having nothing under your heel you leave that end of the arch unstable, which makes it much harder to recruit and use your hips. The back of the arch has to be able to create pressure into something so that the hope can work efficiently. This is why you are told to not come up on your toes when doing deadlifts or squats and to drive through the whole foot, including the heel.  Even OL coaches tell people to “stomp” their heels back down to the ground to get their whole foot stable before the weight starts to come back down and they have to absorb it. If you really needed your ankles to absorb shock then they would cue their athletes to wait until the weight started to come back down and then use the ankles to help catch the weight. And what about the vertical jump, which is the Holy Grail of analogies for this story? What you see during a vertical jump is the ankle moving to get the foot flat so that the hips can absorb the impact. Once again, it is not being used to absorb shock. Another thing that a lo
