I've been looking to get a new pair of trainers for the gym and also for badminton. I've been looking around, but all the big companies have wide categories, like:
1) running shoes
2) basketball shoes
3) gym shoes
What I need is just a trainer that has non-marking soles for when i play badminton, but also quite good for running on the treadmill in the gym. However, alot of the shoes I've seen don't mention if they are marking or non marking soles... so can I assume that all running or gym shoes are non marking?
