Good morning everyone!
I have a problem that I have never experienced before, blackened toe nails! When running any more than 9 or 10 miles in my latest shoes, Brooks's Ghost 11's, the second toes on both feet go black! I've never experienced this before with any other shoes (Mizuno, Pearl Izumi, 361). The shoes feel really comfortable with no sensation of rubbing or tightness. My local run shop is currently closed so I come to you for any insights you may have. Maybe the toe section is too big? I am ready for a new pair anyway having run over 400 miles in them but would be interested to hear of any similar experiences.
