I bought my projumps to run in daily...aswell as the fun factor.
I find I can jog in them for a while but its going to take a while before i can do 2 miles in them.
I also find I have a slight twist on my right leg which can cause my springs to lightly bang when i'm running if I lose concentration and I need to work on that or its going to put me off and cause a fall.
I got reflective tape and led's to go on them too since I might be out on the road.
