I've had my pair of Altos for a few months and love the buuuut, they are definitely too big. I have attached a sports strap which helps but it's not ideal. If any size changes occur could a trade in program or swap out be possible?
Thank you for posting and welcome to the community.
We do have two different sizes available for the Alto Frames. You can find more information about this HERE.
You may find that the smaller size is a better fit for you, so it would definitely be worth trying them out.
While we don't have any official trade-in programmes available for the Frames, I would definitely recommend reaching out to your local support to see what options might be available for you. You can find the contact information at this link, by selecting your country/region and then the 'Contact Us' option at the bottom of the page.
