Great trail running shoe, cushioned but with good ground feel, great energy return and heel-to-toe transition, good grip, surprisingly fast and agile for a large foot and fairly heavy shoe. So why only 4 stars? Firstly the pair I received is not true to size, I bought my regular 10.5 and they are too short, I really needed 11. Secondly the right and left shoes are incompatible in toe size, the right shoe is tighter and there is also a stain next to the first lace hole that is rough and rubs against my toe so it's probably a quality control issue. Please note I have other Saucony shoes including a new pair of Endorphin Speed and they are true to size with no quality issues so I may have just received a bad pair of Xodus. Also note that I love them so much I just ordered a pair of 11 so I can have a pair that will keep my feet from swelling on longer runs/races.
