I've been walking in minimalist shoes for two years now, and also done some running with barefoot shoes on roads and gravel roads - only short runs - 2 to 5 miles, but still, I thought that I had developed some foot strength.
So this spring I started trail running, and loved it. Only 2 miles to begin with, but then I had two longer runs - and now my left foot hurts. The top of the foot, towards the outside of the foot (the 4th and 5th metatarsal if I have got the technical language right.) A dull ache, which is better when I've warmed up and walked/run for a bit, but hurts more after rest and in the morning.
I've been running in pretty minimal shoes. ZEM 360s on treadmill, Inov-8 bare-x light 150 on roads, and Inov-8 trail roc 150 on trails.
I've taken it easy for a few weeks now, and it gets better, but is still there.
So - it seems that I underestimated the strain of trail running with such a minimal shoe as the trail roc 150, and also the difference between gravel roads and uneven trails.
I'm asking for tips here: should I just lay off running - at least trail running for a while?
Or can I start running again, but very short distances?
Finally, should I get a slightly more supportive trail-running shoe? Still zero-drop and wide shoebox...
I've been thinking about the vivobarefoot trail freak (but is it stable enough?), The merrell trail glove 2 (maybe the most likely - but should I get more cushioning?), other merrell zero-drop shoes (ascent 3, maybe?) - or the Altra offerings, such as the lone peak 1.5, or the superior 1.5
So - A complex question, but I'm sure there are some people out there that can answer parts of it!
Thanks!
