These are Saucony Endorphin Speed 3 running shoes. The size is 26.5 cm. They are my go-to favorite shoes. I'm selling them because I bought the Endorphin Speed 4. They can be used for everything from fast jogs to tempo runs, speed training, and full marathons. The outsole is soft and bouncy, but also responsive and provides good rebound. Here's the official description: The Endorphin Collection, which has been attracting attention from many runners since its release. The latest model of the 'Endorphin Speed', which features a nylon plate. This model has updated the sides of the conventional S-shaped nylon plate to a wing shape, which maintains the fit while providing higher rebound than the previous model. Compared to the 'Endorphin Pro', it weighs about 25g more, but the nylon plate allows you to experience more flexibility. The fully redesigned upper provides a comfortable fit from heel to toe. ★ Equipped with 【PWRRUN PB】 ・40% lighter than PWRRUN+. ・Achieves 88% energy return. ・Flexible and durable. ★ 8mm drop (difference in height between toe and heel) ★ MENS: approx. 229g (one shoe), WOMENS: approx. 204g (one shoe) #Saucony #Endorphin #Thicksoled #Marathon #Running #Runningshoes #Runningshoe #Jogging
