Comments: I switched to these when the DS Trainer 19's came out and were way too tight across the toe box (I'd run in 17's and 18's for 4 years). They are a firmer ride than the DS Trainer, and felt lighter. I am not sure how the mileage will compare. I'm pretty lightweight and I think that I am going to max out at just over 300 miles on these shoes. We'll see.
