today we're going to evaluate the hook hook up 11 this is a men's shoes it's a size 10 and it weighs about 11.4 on see it's a very high-profile shoe you notice how thick the midsole lifts your foot is totally high off the ground it has a heel to toe ratio of 30 millimeters and 26 millimeters so you have a poor millimeter offset so the next thing
00:32
we're going to do is we're going to measure the shoe stability index for the shoe and then we're going to tell you who should be in it the first thing we're going to do is we're going to measure a torsional control index or the mid-foot stability what's become so what we're going to do is twist the shoe 15 degrees on this long axis and we're going to measure the amount of inch pounds of resistance that goes through that 15 degrees so let's go ahead with
01:05
this and let's measure this and we have about 60 inch pounds of net foot stability so what we'll do is we'll put that into a mathematical equation but our 60 ok we've calculated that now the next thing we want to do is we want to measure what we call the vertical compression index and that is simply how soft or firm the midsole is under the heel the promo the
02:03
midsole is the more stability in the rear foot the more cushioned the less stability so let's start with this first this computer will measure in millimeters on how soft that shoe is okay with zero the computer and will compress the shoe to a hundred pounds so the vertical compression index or the amount of stability in the rear foot is eight point 18 millimeters okay and
02:57
we'll place job and we have a index for that shoe shoe stability index 52.1 so let's now go over to the chart and see who should be in X you using that index so in between lab testing where we had a constant temperature we don't have it here in this facility it was actually
03:34
41.7 and that would be almost a neutral shoe so if you look at that 41.7 and you compare to the highest it's 92.2 is the highest shoes stability index that we have here taking into account the shoe stability index the person that's probably best to be in that shoe is a person who is a blight stature a hundred and say seventy pounds or less and has a
04:05
neutral gate this shoe does not have enough support for someone who is a moderate to extreme pronator or a stupa Nader the other important part on this is in our lab when we did the rear foot stability or vertical compression index it was 9.24 that is very soft and that is very important to know because if you have someone that has achilles tendonitis heel pain or calf pain you
04:38
don't want them in that shoe because they'll put too much tractional force as the heel drops to nine point 24 millimeters so anyway that's how we evaluate the shoe and if you have any more questions please go to our website ww2 der com
