I had a pair of fit flops over the summer and with being an already active person I didn't notice a difference. However it may be different for someone less active people.
I actually took them back after 8 weeks but only because the instep side of the heel had squished up which was probably due to my supinaion but after only having had them a short while (they were recommended by my orthotist) good old John Lewis refunded me!
Yeah my style is totally different I would show u the video but i've been waiting for it for about 3 weeks! (bit annoying)
The first hour is totally over whelming I thought I was going to pass out after, I was concentrating so hard I didn't breathe!!
They basically teach you to run with your legs in a circle like your cycling so heels up high, knee's up and arms bent at a right angle from elbows and not swinging across your body. This is all done by you running for 30 sec's and then jumping off treadmill for 30 sec's quick discussion i.e think about lifting right heel more.
Its so easy for me to tell you this but actually doing it on a run and knowing your doing it right is the reason why I went.
I have spent almost £1000 on orthotics, physio and massage and feel that running school really is money well spent even though my PT friend tells me I was ripped off!!!
As for being quicker I know I would be but I haven't run outside since February due to all my injuries and I've actually lost all confidence to run again, i'm scared the pain will return!! However I am starting to do a few 20 min runs a weeks but its bloody tough and I find it really annoying how unfit I am!!!!
Anymore questions let me know. I'll post a link to my video whgen I get it!!
