My old Yonex Badminton shoes are on their last legs (forgive the pun!) and begun to start tearing at the seams. I need a new pair of shoes pronto! There are just too options available online and it'd be helpful if someone who knows about shoes could guide me through this maze. I am a heavyset guy (85Kg or 187lbs) with completely flat feet. What would be the best option for me to choose without breaking the bank?
