I'm going to explain something called a TI bar mechanism so the ti bar mechanism of the foot is this um I like to call free because we need to take advantage of it where we have a a ligament that runs across the metatarsals when our foot when we're walking and we go into midfoot loading so when all the pressure comes and our Arch starts to flatten and widen when the forfoot spays it triggers receptors in that deep transverse metatarsal ligament okay the plantar fascia inserts into that ligament so it's kind of like this T so when the foot spays it triggers this mechanism of horizontal stability as well as vertical stability because the planter fascia like a triangle at the for foot now begins to spread under tension while it's also being elongated vertically it's like a fan yeah
