Most athletes buy shoes or boots and use the standard insoles that come with the footwear. Some may know these as inserts rather than insoles. Either word is Ok. Unless there is some reason, the insole is often never removed.
I recently started an interesting experiment. It is unscientific, but it is relatively straightforward. I was sent two pairs of replacement insoles to try. The one pair is made for people who stand for long periods of time, especially on hard surfaces. The other pair is made for general use. The insoles were from MEGAComfort.
My stock of insoles includes SuperFeet, Spenco, Montrail, ShockDoctor, and more. Last November I started playing golf. My wife and I usually play 18 holes each weekend—walking, with a pushcart. Each time I play, I wear different insoles, and sometimes use different insoles in each shoe. So far, I have used three different insoles. I have found the insoles often feel quite different. In the weeks ahead, I will continue this little experiment and report on my findings.
I will give you a heads up, in case you are still using the insoles that came with your shoes, there can be a huge difference in how insoles feel.
