I have built my daily walk up to almost 2.5 miles in 45 minutes or so. I had to stop wearing my New Balance M993s, as they were hurting my feet due to the toebox too tight, even in a wide size, and some funky motion issues with my right foot. I went back to Merrell Moab Mids last week. I know they aren't ideal for sidewalks, but they feel stable and comfy for boots. New Balance has agreed to give me a credit for returning them, though. Now that the miles are adding up, I feel like I have a burning pain in my right forefoot pad when standing and walking. My Googling has turned up Morton's Neroma as a possible issue. I k one thing, I love walking, and I don't want this to stop me.
