I’m confused, what did you do?
A few weeks ago I used the Boa warranty page to request a replacement for my 2015 Specialized Audax shoes. I picked the wrong replacement, and Boa sent me gen2. I emailed Boa support, explained the issue, offered to return the gen2, included a more detailed photo with my best guess on the correct replacement, and they sent the correct Boa gen1 (believe there are 4 different versions of gen1). They also told me to not return the gen2 Boas sent because of my mistake.
So I’m confused because at least in the US, they will ship warranty replacements immediately, and if you screw up, a simple email should get you the correct replacement.
