so i ran in them...and it was great! now mind you, i do most (ok, really at this point ALL) training on a treadmill in my mom's room in front of the tv (while usually watching duggars or dc cupcakes, or, when it is in season, the biggest loser). so anyways, i run on a treadmill. but they were great! i actually ran my fastest mile ever in them....7:27! that was a big deal and i was quite proud. i took them off after the first mile because i am going to ease myself into them (per recommendation of vibram's website). i really enjoyed running in them- after i got over the initial first few awkward strides. i can't wait to run outside in them. the one thing they really made me notice was how much i slam my heels down when i run- need to work on correcting that. after changing out of them after the first mile, i went on to run my fasted 5k ever- 23:50! proud moment :)
so yeah, i recommend them for sure!
