I initially bought the ultra gel Insoles. I suffer badly from numb and painful feet and I am on my feet all day. I am sorry to say they were useless. However I contacted the company and gave them the details of a previous product of yours I had had a lot of success with. A lady called Alyson offered me a refund on the ultra gels as I had bought three sets but it involved returning them and this was too much trouble so I just threw them away. She advised me how to find the Aero 3 s I had been looking for but could not find as they are not featured on your website. ( I did not know them by name),. I then bought four pairs and have been extremely happy ever since. These insoles are a life changing product giving swift and effective relief and comfort. Vital improvements to my feet as a diabetic. Well done Wellbury. My advice would be feature this product on your website, it is the best and cease production of the ultra gels, they don't work.
