not sure how to make a direct comment to one of the existing comments above, but this is to Amarsh04. I like your idea and the sketch is super clean, but the concept may be a bit shortsighted. Riders already have booties they put over their shoes which are removable, for a reason. I’m not sure if you ride/race much but an 80mile ride may start out raining or windy/cold and by hour 3 its hot and sunny, you won’t want the entire wet and cold shoe booty flapping, unzipped, from your ankles for the remainder of the ride. Maybe if you could improve the integration of the booty & shoe itself, instead of having to use an entire “sock” that covers the whole shoe something smaller and more compact could be used. I dunno, that’s just what came to mind when I saw your idea…
doodling,… it’s a hell of a drug.
