OMG I literally just bought the Proto Speed trainers, and they are the best shoes I have ever owned!! I haven't ran in them yet, but I did Cardio Fusion yesterday. They are super cushy and supportive. They have elastic attaching the tongue to the shoe, so they don't slip down. I have super narrow feet, and these are the only shoes that don't have tons of extra space by my toes. They definitely have my vote!!!
