Amerigo flexi stirrups????

[air78]

Have i imagined that these exist!

I am sure that i saw these on some website or another some time ago- they could have also had cheese grater treads- and now i can't find them!

Am i going mad, or does someone know where i have seen them, or, even better any opinions on them.

Can't help except to suggest a Google search or perhaps have a look on eBay?
