Yes this is a Retül add, but from experience it’s right to support your foot in your shoes with a cycling perspective insole in your flat or SPD shoes.
For me I need a middle arch support in my left shoe and a high arch support in my right shoe.
I had to travel to Australia in 2017 to learn this but you don’t.
See any good bikefitter in your local town/city, or your can go to one of a number of Retül bike fitters around NZ.
Happy cycling all.
