can anyone recommend the perfect pair of trainers fir me run? It covers multi terrain. Some gravel path, moors, muddy hill, a couple of miles of road and a couple of miles of fell path. I find my road trainers work well on the fell path but my Solomon soeedcross trainers are very slippery on the fell path in wet weather making it hard work. I like a bit of cushioning for the road and I’m getting older so I need to be kind to my joints. Any recommendations much appreciated!
