a 96% satisfaction rate for sore feet worldwide
“I got introduced to MASS4D by one of my neighbours who had used the product himself. I’ve been wearing it for the last 8-9 months. I ran a marathon with the insoles in my shoes. I’ve had no more pain in my feet.”
— Oliver Castillo, Student
“It’s a comfortable thing to wear. It’s really helped me and I can tell it’s helping the power output as well in my cycling. In terms of marginal gains, I think we’re there with MASS4D and it has certainly helped.”
— Manish Pandey, Sales Consultant
“Most people try to use ice or foot massages for reducing much of their foot pain. I think by becoming aware of and using products such as MASS4D, the running community can benefit a lot.”
— Aida Abbasi, Artist
