Started running with forefoot landing 1 1/2 years ago. First with VFF, some barefoot when conditions allowed. Went to New Balance MT20v1 for winter running as I needed a thicker sole for the hard frozen ground. Ran last winter with no problems but found this year that the sole was not thick enough to prevent some discomfort when landing on embedded rocks in the frozen shoulder of the road. This new version has a little thicker sole which is more forgiving although not as flexible, an acceptable trade-off.
