Have you been missing out, not knowing your blood oxygen levels on an hourly basis this entire time?
!But top of the heap of seemingly unnecessary complication must go to thebest running shoes.
Uppers, midsoles, foam, energy return, outsoles… the list goes on.
It seems that running shoes are just as carefully designed as electronics.
Which, when you think about it, makes a lot of sense.
To make a long story short, we have an upper and a bottom unit.
The upper [focuses on] protection, fit, and comfort.
And then we have an outsole, which is for traction and for durability.
Below, Miles goes into each part in more detail.
The upper
Miles describes the upper unit as a combination of lots of different pieces.
If you have a wide foot, look for the wide keyword.
Dont be fooled by the way it looks!
A shoe that’s slightly shorter but stretches more still might fit better.
If it stretches, it might be just right.
Its always removable, which is also important in case you have an orthotic insole to replace it.
The midsole
We call [the midsole] kind of the engine room of the shoe.
This midsole usually will be made up of foam.
When we talk midsole, what we talk about here is the properties of cushioning.
Cushioning is deformation., Miles tells us.
You put force into the ground, and the ground gives you that force back.
You’ll see across a lot of shoes that we talk about energy return.
They get that in their next step.
The outsole
The outsole has two very distinct purposes.
First, traction in wet and dry conditions.
And that’s also something that we pride ourselves on at Adidas.
