PUMA DEVIATE NITRO ELITE3 Puma Deviate Nitro Elite 3 World Major Marathon Model Men's 27.5cm Mileage: Approximately 100km Racing shoes equipped with a carbon plate. The midsole is 4mm thicker than the previous model, yet the weight is only 194g (27cm). This is Puma's lightest racing shoe ever, and its overwhelming speed will help you achieve a personal best. At the U.S. Olympic Marathon Trials held in February this year, Fiona O'Keeffe, wearing the "Deviate Nitro Elite 3," won with a time of 2 hours 22 minutes 10 seconds, securing her place as a representative for the women's marathon. I think this is a very good shoe for those aiming for a target time faster than sub-3.5.
