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
