Why running shoes have extra holes

By Phil Clark / May 26, 2018

For more than 100 years, shoe manufacturers have been giving their customers ways to modify the way that shoes are laced. Just about all shoes come with a standard crisscross pattern. Additional loops, hooks, and related features allow us to modify that standard lacing, as necessary.     The eyelets at the very top of…

Do some running shoes slow you down?

By Phil Clark / May 19, 2018

We currently sell shoes by Asics, Brooks, Saucony, Mizuno, New Balance, Under Armour, Hoka, and Adidas. Not one of those manufacturers claims that any of their shoes will make you run faster—or slow you down. But that doesn’t stop consumers, especially track racers, for making the claim that the lighter the shoe, the faster you…

Is there a major difference between men’s and women’s running shoes?

By Phil Clark / May 12, 2018

Just about every shoe that we sell carries the same name in both men’s and women’s running shoes. The Saucony Guide ISO is called by that same name in both men’s and women’s, for example. But the same name does not mean the same shoe. Here are some obvious, but nonetheless very important differences.  …

What is gait and does it matter?

Why EVA in running shoes is important

By Phil Clark / April 28, 2018

On our wall, just about every shoe is made with some kind of etheylne vinyl acetate (EVA). During the history of the technical running shoe, EVA has become the preferred material for midsoles and sockliners. EVA is the prominent material in most technical running shoes. It’s a foam that can compress without flattening under large…

Don’t machine-wash dirty running shoes

By Phil Clark / April 21, 2018

I have a 1970’s memory of my mom using the washing machine to clean my shoes. (Don’t ask me what kind of shoes they were, I didn’t know if I was wearing dirty running shoes or basketball shoes or tennis shoes–as long as they weren’t the dreaded bobo shoes!) They didn’t fit exactly like before…

Does Under Armour make good running shoes?

By Phil Clark / April 15, 2018

I have a high regard for the companies that manufacture technical running shoes, which are shoes made specifically for running. There are not many of those companies that are recognized around the world. Under Armour is now among their number. Making a durable technical running shoe is hard because running causes forces that punish shoes.…

Do I need insoles for my running shoes?

Here are the three kinds of insoles that are commonly put into technical running shoes, in descending order of importance: manufacturer’s insoles, orthotics, and off-the-shelf insoles. The manufacturer’s insole is the most common type. Manufacturer’s put insoles into almost all technical running shoes. Of the 62 different styles of technical running shoes that we currently…

What makes HOKA ONE ONE shoes different?

By Phil Clark / March 31, 2018

HOKA ONE ONE, like every other shoe manufacturer, boasts a number of different technologies. HOKA shoes have one, very recognizable feature: a very large amount of cushioning underfoot. They also shape their midsoles to mimic a rocker, so that the shoe helps drive you forward.   The main advantage     But the technology that…

Why do arch supports hurt my feet?

By Phil Clark / March 24, 2018

Arch supports probably don’t hurt your feet. Size and width explain much of what makes shoes comfortable and also explain much of what makes shoes painful. Pain, even in the arch, is most likely due to too little room, not to arch supports. A foot has three arches Biomechanists sometimes describe the foot as having…
