Again, you will run faster with VFs on your feet than any other footwear in existence, regardless of surface. This is a proven fact. Tests were done on a treadmill and all evidence points to them leading to faster times. Only a fool wouldn't wear them for any race that is 5 or 10k regardless of surface.
This above statement is totally incorrect.
VFs will not be faster than spikes for soft, slick, muddy, snowy cross country races.
They will not be faster for trail and mountain races with lots of rocks or roots.
They will not be faster on snow, ice, or wearing them in snowshoe races.
They would not be faster for fell running, vertical kilometer races, races like Mt. Marathon in AK, etc.
Going beyond 5 and 10k, they are unproven for races like Pikes Peak, The Barkley, Sierre Zinal, Western States 100, UTMB.
VFs have very poor traction and stability. They are only good for dry, consistent, smooth, hard, flatter surfaces.
I question how efficient they are for uphills, such as Mt. Washington.
VFs for XC is asking for a rolled ankle?
