Plates training shoes are an effective simulation of what you will be racing in. For track workouts, it can be nice to have a carbon plate to make your landing not feel so squishy and saggy. The plates shoes are more expensive though than most non-plates trainers. Depending on your biomechanics, a carbon plate can be overused and lead to an injury in the long term.
I’d say that if you would really like to try training in a carbon plated shoe, do so for your faster workouts first. If you’re the kind of person who wants one and only one shoe to do everything, don’t train carbon plated. It can just become too much, especially on easy runs. But if you have a rotation, I’d say fill in a spot with a carbon plated training shoe!
