Hello.
Now I can't choose which shoes I'm using for my runs.
Let's say I change shoes after 500 km. So now I'm using the goal option to count.
But if I have 2 pairs i have no option to count the km. for each pair.
I suggest you can add another optional field in the activities where i can log the shoes, and later i can request a report for total km. for each pair.
P.S. Sorry for my bad English :)
