Saucony Endorphin Trail Mid Women's Running Boots Taking Saucony's revolutionary SPEEDROLL technology off-road for the first time, the Endorphin Trails are destined to deliver you a running experience like no other. FORMFIT Upper The upper of the Saucony Endorphin Trail Running Boots are made from Saucony's revolutionary FORMFIT technology. This breathable mesh upper expels heat and vapour through micro-perforations, whilst simultaneously allowing fresh air to flow in for a pleasant cooling sensation that will keep your feet feeling fresh and dry. The mesh construction is incredibly supportive, wrapping the foot in 3D comfort for a personalised, secure fit that keeps you in control. This added stability will help you tackle the trail in confidence, whilst the quick-fit trail sleeve protects feet against dirt and debris, helping to shield you from any sharp rocks you may encounter. Additionally, the mid-height of the boots provides your feet added protection and support for a range of trail running terrains. A traditional lacing system works in tandem with the FORMFIT tech, locking down the foot, whilst an incorporated D ring allows for gaiter compatibility when you most need it. PWRRUN PB Foam Midsole Get incredible spring and return from a thick bed of ultralight PWRRUN PB cushioning. This midsole works to cushion the foot on impact, reducing the stress and strain your feet endure, meaning a reduced risk of injury as your feet are protected. The midsole also works to provide a springy rebound, utilising the force from your last step to power you into your next one. This results in less energy loss and a reduced rate of fatigue, meaning you can go further faster. SPEEDROLL Rocker Technology helps to further propel you forward, giving you continuous momentum to help you get that athletic edge, helping you to run faster, without having to work harder. A durable net mesh covers the midsole area to protect it from the rugged terrain, resulting in long-wearing, durable performance. PWRTRAC Outsole Completing the boots are an ultra-grippy PWRTRAC outsole that also has an ascent/descent-friendly lug configuration for ultimate levels of control. This means take-offs, turns and stops are super responsive, and you can run in confidence knowing your boot can handle variable terrain with ease. The thin but mighty outsole provides a plethora of benefits without the added bulk or weight, so you feel unstoppable - whatever your adventure has in store.
