thank you
by any chance u know whr can i possibly buy these shoes (authentic ones) with cheaper price?

if buying sneakers just for fashion, then anything will be alright. if for serious running, I recommend a very good site that gives serious reviews on running shoes, you'd be surprised that many flashy brands got thrashed, they spent their own $$$ to buy the shoes for testing, sometimes they even cut open the shoes to check the component materials. Some big name brands got criticized heavily for not being honest!!! Really worth checking this out for serious runners:

http://www.solereview.com/list-of-performance-reviews/

The current highest rated products are Saucony Ride 7, New Balance 1500 V1, Nike Air Pegasus 31, Brooks Adrenaline GTS 14, and those Adidas Boost series.

The Pegasus is a brilliant choice for running, consistently rated highly after the refresh. Pegasus 32 on sale now, 300 or so. Very similar to the 31. Note that the air bag at the heel though so more cushion for heel strikers, if you a forefoot striker better get the zoom elite 8.

They're fine for walking, but a bit uncomfortable relatively I feel because they tend to be stiff to absorb heavy impact. So for say, whole day walking I tend to avoid them.
They're available mostly at jerasia run Nike boutiques. Should be in most major malls I think.

I feel roshe runs have more cushioning for walking, the older ones with the solarsoft insole. Compared to Nike running shoes that is. Able to walk a full day with slight soreness in foot, compared to heel really aching if walking in Nike running shoes.

glad it helps. I just searched for reviews on a shoe and accidentally found this link http://www.solereview.com/list-of-performance-reviews/

i'm quite surprised to learn that newer models may not be better than an older version, like:

Asics Gel Kayano 20 - 87
Asics Gel Kayano 21 - 85
Asics Gel Kayano 22 - 66

Brooks Adrenaline GTS 14 - 90
Brooks Adrenaline GTS 15 - 88

Nike Air Pegasus 30 - 87
Nike Air Pegasus 31 - 94
Nike Air Pegasus 32 - 85

Saucony Ride 8 - 83
Saucony Ride 7 - 95

compared with other major review sites like runnersworld, this solereview's reviews are more in depth and serious. of course, any review we shouldn't treat like absolute truth, but rather as a very good reference.

happy hunting!!
