Hi my name is Philip Vasyli, I'm an Australian Podiatrist and I've been in practice for over 25 years. I'm the inventor of the Orthaheel product range and I designed these products to treat excess pronation. Now excess pronation has been commonly linked to aches and pains like heel pain, knee pain and even back pain. So, if you're suffering from any of these conditions, I encourage you to give these products a try. Thank you. You can see I've drawn a line down the front of Lauren's leg or tibia as we call it. Right through the ankle, through the foot to the second toe, second metatarsal joint. I've also drawn a dot on Lauren's knee, so you can see the rotation of the knee and have the how the foot effects it. Now if you look at Lauren, she's standing on hard flat ground, which commonly causes excess pronation rolling over the foot, which is this sort of curve in here. Now if you have the foot, the way I would like it, in this sort of curve, if she stood on soft natural surface like ground, support her foot, you can see how the line is much more straightened and the knee now lines up with the ankle right through the second toe. You let her foot relax, you can see how it rolls in and you get this excess pronation, which commonly causes aches and pains like heel pain, tired aching legs, knee pain and even back pain. We turn the foot to the side, you see how the arch is also very collapsed. Again, if I correct the foot, watch the arch, you'd see a great improvement of the height of the arch. And this is how we'd like to keep her foot, but unfortunately with standing on hard that ground, this allows the foot to roll in, which in turn collapses the arch. Now if you get Lauren to stand on the Orthaheel product, you'll see from the front view, a very nice correction of the alignment, straight from the second toe, through the ankle right up through to the knee. If you look at the side profile, you'll see the heel is nicely cupped, which holds the heel in alignment and the arch is contoured right up through the mid foot, stabilizing the whole heel, mid foot and fore foot. Now if you take that off again, look at the arch, you'll see how it collapses and again many people wear flat sandals, like this. If Lauren puts this on you'll see, that provides no support, no correction and again if you look from the front, the same scenario of the excess pronation. Take the product off, put Orthaheel product again and look at the great improvement of the alignment. Nice alignment from the mid foot, arch, right up through the leg and knee and again, looking at the arch, the heel contour is beautiful and so is the arch contour right, through the whole foot.
