Your running shoes came with a thin foam insole. Around 10 to 20 miles in, it's already packed flat. The shoe still looks new. It just doesn't feel like it.

Get an insole made from foam that springs back, with an arch that matches your foot and a top that keeps you from sliding on turns and downhills. Ours are 85% ETPU midsole foam, with 14% higher energy return and 17% more cushioning vs. the average aftermarket insole, and a 1,000-mile cushioning guarantee.
Most insoles are EVA foam. It feels soft out of the box, then it compresses and stays that way. That's the dead feeling you get a month into a new pair of shoes.
We build ours on ETPU midsole foam. It springs back after every step instead of packing down.
Then there's the slide. On a downhill or a sharp turn, your foot moves forward in the shoe. Our NonSlip top holds your sock in place so your foot stays where you laced it.
“I've put ~600 miles on my first pair, and they're still performing.”
“Held up great in a wet 50-mile race... About 120 miles so far, still great cushioning.”
“Running once again feels like it should. When my feet hit the ground they roll and lift rather than pound the pavement.”
“I'm an ultra trail runner (60+ miles per week)... first use, I noticed a big difference.”
“Putting these into a pair of my running shoes makes them feel like almost brand new! My foot doesn't shift around inside of the shoe.”
“I'll continue to use the max cushion for daily runs... I like that [the low profile] feel a little more responsive and my feet feel a little closer to the ground.”
Reviews are great, but we wanted numbers too. So we put athletes through independent biomechanical performance testing. Here's what came back.
In independent biomechanical performance testing. See the full data.
Our pick for most runners. The grippy top keeps your foot planted on turns and downhills. Max Cushion for daily miles, Low Profile for races and track days. Low, medium or high arch.
The same ETPU foam and arch support with a standard top, if you don't want the grip.
Pull out the insole your shoes came with and drop ours in. That's it for most shoes. They fit 97% of them.
If yours runs a little long, trace the old insole on top and trim along the line. Just know a trimmed pair can't be returned, so try them in the shoe first.
One tip from a customer: the top really does grip your sock. Slide your foot in rather than jamming it, and your sock stays where it should.
