Has anyone here tried treadmill running with the VFF's? I'm interested in trying them, but I don't do cold-weather running due to my asthma. All of my running during the winter months, is done on the gym treadmills. I'm just wondering if I would reap the same benefits using them on a TM vs. outdoor running? I understand the need to build up slowly with them...so what would be an ideal amount of time/mileage for my first run in them? I typically run shod, for about 30-40 minutes at a 5.7 - 6.0mph pace...so, at a 10+ minute per mile pace, I'm pretty slow. My lower back simply cannot handle a higher running pace...so this is the range at where I stay for all of my runs.
