The Clifton line has always been my favorite road trainer with an excellent balance of lightweight and comfort. They have come a long way since the first version I purchased in 2015 with big improvements in each iteration (These are 15% lighter than the previous version). You'll find the fit true to size with a generous upper allowing the toes to splay out. Perfect for paved and dirt roads and can even get you through small portions of non-technical trail (I wore these for the Ragged 50k one year).
