The one I use.

which model are those?

heh I use some older new balance shoes or my old work boots with thick wool socks. the socks give me extra cusioning and the boots can stand up to the need to be able to take impact fromt he enviroments.... But if your on like the fake plastic floors and have freash mud you might slip a little XD

um any recomdations for a size 12 wide that isn't teribbly expensive like under the pegasus' $80.00 price tag
any suggestions would be appreciated.

I used extensively worn down skate shoes for PK at first, they felt fine, they had no grip on the shoe, although i could grip better than others who had big grippy shoes somehow.

But I decided to buy some Nike Air Pegasus due to fear of getting knne/ankle problems from not having shock absorbing shoes. Firstly i felt like i was walking differently, everything felt too cushioned and i could walk alot more quieltly in my skate shoes. I tried doing all the things i usually did in my skate shoes.

 I had less grip/found it alot harder to grip properly. Wall-runs were much harder. Balancing was badly effected due the all the grip on the underneath of the shoe.
 Landings felt slighlty heavier, didnt feel right, and also they sounded much heavier.
 When running on a treadmill, i felt that i was running differently, even the gym instructor said i was running wrongly. And ive never had problems with running properly.
 Overall i felt that i was restricted, and that i could not use my feet properly.

When i switched back to my tatty old skate shoes, i could balance no problem, felt like i was walking properly, my landings had to take a teeny while to adjust back to normal, and grip was a million times better. I think that grip is not too important on shoes (unless it is wet or something), and that its the way you use your feet that enables you to grip better.

eig s i am really new young and running on a low budget do you have anything in mid in youth sizes cheap and long lasting i don't mind any other drawbacks

skate shoes are extremely durable, don't get me wrong...but their shock cushion is minimal, sole is too soft, support is next to none, and they come off real easily.

TO ALL: 5.10 SAVANT'S ARE THE WAY TO GO. extremely sticky climbing rubber, lightweight, very breathable, durability unmatched (made for climbing approach and light hiking), cushioning very good, wide and nearly flat sole, support unbelievable. this is the most advanced shoe available for parkour, i think. rumor has it that 5.10 is making a new parkour-specific shoe. i highly highly recommend them. they will last a long time, so the 75 bucks is well worh it. 

On concrete, the grip of a shoe is based on the kind of rubber it has and the amount of rubber it can put on the ground. In the dirt, points and lugs in the tread will dig into the dirt and give you better traction but on hard smooth ground they will prevent you from putting rubber on the ground. More surface contact=more friction=more grip. This is why I don't think trail runners would make optimum parkour shoes, because they tend to have more lugs for grip on dirt. That is also why your worn down skate shoes gave you more grip, it's because you were able to put more rubber onto the wall. Keep this in mind when looking at shoes. Flatter tread will give you more friction.
