Hi I have been wearing my running shoes for FB workouts. With 2 outcomes. 1. my running shoes have lost all their treads 2. I have tendonitis in my achilles and an ingrowing big toe nail. Both I think due to wearing inappropriate support for lateral moves and insufficient cushioning for all those jumping moves! What is your recommendation for shoes I should buy? I am on a budget since I also need new running trainers now ;-)! Thanks for the recommendations
