Ridiculous, felt it rubbing in mile 1. Yet again my feet always cause problems, and I can't buy another pair of shoes! I was wearing Ininji toe socks as well. I would love to increase my distance to marathon but not sure my feet could take it. Just a vent really, I am an experienced long distance runner but it seems my feet have changed shape over the years. I've been through so many shoes, I get a size up and usually wide fitting. I heel lock lace them too.
