There needs to be a better way to indicate what shoes were worn on a given run. Most people rotate their footware so just selecting a default shoe isn't of value. I actually have my activities uploaded to RunningAhead just so that I can keep accurate mileage statistics on my shoes. It would seem a simple matter to just put a dropdown list box on the activity screen.
Yes, default options for gears should be more detailed.
There are only main types to choose - like gear default for Running. And then that gear is connected with all running activities: Outdoor and Indoor. And that's bad, usually we use different shoes indoor.
About dropdown list, there is one when you open some activity and click on blue dot with number (Gear), then you can remove default gear and choose another. But you need to change that for all activities one by one.
So, yes, it would be nice to have dropdown list on main activities screen to temporary choose gear for some consecutive activities of choosen type. Useful if you make few activities per day and also change gear daily.
