“I have been wearing only Gravity Defyer shoes for at least the last 7 years-for work and leisure. It's the only shoe I can wear and still be able to function - I have arthritis in every joint and these shoes have helped me in so many ways!! I do have a question...the ones I most recently got are "different"...the sole is very hard and I don't know if it's the style or if the manufacturing process has changed? All of my other pairs are extremely comfortable from the time I put them on but I've noticed with these, I feel my foot 'slapping' the ground instead of the normal, cushy feel that I'm used to. I'm hoping they just need to be broken in but I've never had to do that with any of the other styles I've worn and I've tried all of the non slip styles and never had a problem. I walk an average of 8 miles everyday at work and if I would've never tried Gravity Defyer, I would've been forced to retire years ago! I will never wear anything else!!”
