High speed treadmills are used to increase turnover at the expense of decreasing your stride length. They reduce your stride length by decreasing impulse. The key to developing speed is increasing impulse. This video shows how to increase your stride length by increasing impulse using a standard motorized treadmill.
The thinner shoes are lighter, which is what most runners are after, but a thinner shoes has the benefits of letting the foot operate better. One of those benefits is a less materiel to interfere with the arch of the foot and the plantar fascia working properly. Another benefit is less rubber to restrict the flexing action of the foot. The better the foot operates the less energy used at speed.

This becomes the issue, you can have heel recovery two ways, by using the hamstrings which is what most people do and becomes very tiring after a while or you can doris flex your toes as your foot leaves the ground, which is an more energy efficient running action. Dorsiflex toes is better than a dorsi flex foot.. There is a difference. Once again due to the type of shoe you wear, the ability to dorsi flex your toes my be restricted, especially with a show with a narrow toe box area.

I am trying to go sub 1:26 on my next half marathon. For me, running 7:30+ min pace doing high heel recovery is tough and tiring but doing high heal recovery seems to help a lot on my tempo runs, 6:30min pace. P.S thx for your reply

So, thats why most fast runners use race flat shoes. thx

Heel recovery is speed dependent. For some that may be a fast speed so yes the heel recovery should be high for others that may be slow speed so heel recovery wont be as high.

Not necessarily. The faster you go the shorter the ground contact time regardless of landing on your heel or ball of foot. What changes from landing on your heel or ball of foot is your stride length. Heel landing decreases stride length and ball of the foot landing increases it. Now most shoes shorten the time you spend on the ball of the foot., which doesn't let you maximize your stride length.

Doesn't landing on the ball of the foot decrease the ground contact time? Is high heel recovery always good even at slow pace, 6mph? Anyway, your form looks really good.

180 strides per minutes at 8:00 pace is only a 44 inch stride length, which is a very short stride.
Your theory might be correct, but not with such a short stride, which makes the impulse a greater percentage not less.

It does work if you know what to do and how to do it.

this doesn't work... (take it from a 15year old sprinter)
