Feature Request: Add support for multiple shoes at one (running) activity
Reasoning: Usually at some type of training I use different shoes to warmup/cool down, and a different shoes pair to the main focus of that training. It would be great to have a feature to choose multiple shoes pairs for a single activity. Allowing to choose the activity time when we swap them to give the correct KMs for each pair. For example: Pair 1 from 00:00 to 15:00 (4 KM), Pair 2 from 15:01 to 40:00 (8 KM), Pair 1 from 40:01 to 50:00 (2,5 KM). It will add 6,5KM to the Kilometrage of Pair 1 and 8 KM to the Kilometrage of Pair 2.
