I am in high school and searching for a new trainer shoes for the winter season. I have used Saucony mainly for trainers. Back in the summer I was in Kinvaras and then trained in Rides for the cross country season. I recently got another pair of Rides but they have been messing with my toes and don't feel the same as the other pair (it's the exact same model). Are Kinvaras good for training or are they more of a racer? I don't want to train in super light shoes and then get to competition day and have my spikes not feel any different!
