![]() That is normally where you can pivot and power off as long as Rolling off a collapsed first ray is not a Some people may never have a problem however and it depends on the resiliency of the person.įorefoot medial flare is a favorite of mine as it tends to resist forefoot pronation or collapse. For shoes with a great deal of lateral forefoot flare, many forefoot strikers need to be wary or at least understand why they may or may not be having some initial discomfort (sometimes iliotibial band issues from my experience with a few patients). Most individuals however wear this down fairly quickly in shoes with minor forefoot flare and then don't notice it. This can lead to excessive joint loading and a little extra muscle strain potentially in the peroneus longus or posterior tibialis, as both have a longer direction to fall and attempt to eccentrically control. Early initial contact is again not usually a good thing because you are hitting the ground before your muscles and body are ready to properly absorb force. Similar to the lateral heel flare, lateral forefoot flare can cause early initial contact during a forefoot strike. I do not have a study to cite on that).įor those that forefoot strike on the lateral edge of the forefoot, forefoot flare may not be a good thing. Stress fractures (that last one is anecdotal. Yourself as well off these joints or potentially place yourself at risk for Overuse the lateral structures of the foot, waste energy as you cannot propel Stabilization at those joints means you are either setting yourself up to The 4thĪnd 5th metatarsals are not so tough and given the lack of muscular Is a much more robust joint that can take a great deal of force if applied in the correct plane of motion (sagittal). Very important place for you to lever off of during toe off. Hold 1st metatarsal down and propel off of it, so people avoid loading it. Weakness of this muscle causes an inability to Excessive inversion of the forefoot at late stance or toe off mayĬause excessive loading of 4th and 5th metatarsals and usually I find there is weakness Supination or more accurately excessive forefoot inversion at late stance Forefoot lateral flare generally resists excessive late stage Like the heel, the forefoot of a shoe can have lateral, medial or both kinds ofįlare. ![]() An early contact means they are not fully ready and thus your shock absorption has to be compensated for (usually by joint loading). Your muscles should optimally be activated before you land to prepare for shock absorption. So for those with posterior tibialis issues, lateral heel flare is something to avoid because it means the posterior tibialis has to work over a greater distance AND you land when your muscles are not ready to absorb shock. Early initial contact however is not good because your muscles are not ready to absorb impact and it increases amount of distance your foot has to pronate. It is normal to land at the posterior lateral heel (not the posterior medial). The reason being is that lateral heel flare with normal mechanics causes an early initial contact with normal landing in a slightly inverted foot position. However, individuals that land laterally and pronate naturally need to be careful of excessive lateral heel flare. Given that it is rare to find actual secondĭensity foam or posting for supination, lateral sole flare tends to be a moreĬommon shoe feature that can help with this. Motion, not shoe wear, which is poorly correlated with little to no research on outsole wear patterns. Just because you wear out the lateral side of you shoe does not A great many individuals assume they supinate,īut what usually happens is that they land in an inverted foot position causing them to land on the outside of their foot and then they pronate (which is fairly normal). This may be due to the fact that supination tends to be a much more Really any running shoes specifically made for excessive supination of theįoot. With the exceptions of the shoes mentioned above, there are not More material on outside of the shoe that serves to resist the outward role of ![]() Like medial sole flare, lateral sole flare creates Supination generally involves the laterally directed roll of the foot upon contactĪnd loading response. In the heel is one of the few ways to resist supination at heel contact.
