I've been using one since July and its brilliant for my calves and helping with an Achilles niggle. I should use it every day and its supposed to be good for a warm up too
I've been using Nike 3.0 trainers since January about 20 miles a week on streets and in wood trails and and love them but lately I've been having a few niggles in my Achilles and back. I assumed that as they are not shoes that provide support I wouldn't need to change them as you would normal running shoes. Am I right or wrong in my assumption here? Any opinions?
