New Balance 807

New Balance has the EEEE size that I need. The 807s have a stiff enough sole to run over sharp 1 - 2 inch rocks without any discomfort or bruising. The soles have good grip as long as you avoid any frozen or frosty surface where they are super-slick. These are the second NB trail runners that I've had. Fortunately this model does not have the hard plastic inserts on the sole instep found on some other NB runners that are destroyed by sharp rocks at cold temperatures.
