As an intermediate badminton player i can say that these shoes are best if you are just starting plating badminton (beginner) The only problem is that if you play for more than 1 hour while wearing them they will look like stove you can make any dish you want ..and probably you will need a 🧯to make stove off. Paint is okay it will start shading after 2 or 3 months depends on your uses(it is no big deal)
Overall if you are starter and looking for non marking shoes you should go with them...
