If you like to mix up your training with both road and trail work, the New Balance Men's MR810 Trail Running Shoe is a choice that's hard to pass up. The proprietary Ndurance rubber compound outsole with AT Tread pattern performs brilliantly on hard or soft surfaces. It's plenty durable for logging high mileage on roads or rocky surfaces, while the tread pattern gives you a sense of confidence even when a week of wet weather turns your favorite trail into a minefield of mud puddles. Although the Abzorb EX heel pad features a pocket of non-pressurized air for exceptional cushioning on hard surface runs, this sort of technology never hurts if you're chalking up plenty of miles on trails. The New Balance MR810 Trail Running Shoe's synthetic, mesh upper provides comforting ventilation in the most demanding conditions, such as those lunch hour runs when you brave the heat just to get your running fix.
