Bit of a mixed experience in that I had used aero 3 insoles for a long time and they are super comfortable and long and hard wearing. I tried to purchase these from the website and couldn't as I didn't know their name at the time and there were no photos of this particular product. I bought Ultra gels instead. These were nowhere near as good sadly. I wrote to Alyson who offered a refund if I returned the ultra gels which is fine but, frankly I can't be bothered. However she told me you still do ultra gels so I'm ordering some more of those. My advice would be: they are by far your best boot liner, put them on your website, I'm an Art tutor on my feet all day, I also ride motorcycle trials and I use them for both. I would happily write you a powerful testimonial for this product they are fabulous. The ultra gels, well, not so much . Best regards Jon Dent
