How do i know what type of foot strike i have?

I would recommend going to a good running store and having a gait analysis if possible.  They will let you know if you are a neutral, mild pronator, or sever pronator and suggest shoes accordingly.  That does not mean that you have to purchase from them of course, but it will help you figure out your question.

Zoot only has two styles.  The Tempo and Race which are designed for neutral runners and the other one designed for mild pronators.

If you look at the soles of the shoe, you can usually see where there is more excessive wear.

well i live in a rather small town and have only 1 running store and they don't do gait analysis.

looking at my Vomero's, i really don't see any excessive wear in any one spot.

Then you are probably landing flat (which is what some would call mid-foot) underneath yourself and not with your foot turned in or out .... in other words, neutral.

But that is a total guess and I would not bank on that without having someone look at it!

Yeah, it's not the best. I'd call it a quick and dirty method of discovering what type of strike you have. The best is to just get a gait analysis.  

Almost everybody lands on the outside of the foot and rolls inward (pronation).  This is the 'natural' running gait, and it is how the body absorbs the shock of the foot strike.  Actually landing on the inside of your foot is probably a fast road to injury.

Briefly: 

over-pronation: rolling in too far

under-pronation:  not rolling in enough

Some people use the term supination as a synonym for under-pronation.  Others say (more correctly, if the academics are to be taken as authorities here) that supination refers to the slight outward rolling of the foot on the push-off.  This is also natural.  Do it too much and you 'over-supinate' (far enough, and you'll roll your ankle), not enough and you 'under-supinate' (those terms are only rarely used).

You don't need cameras.

Go to the running store.  Tell them you are looking for new shoes.  Show them your current pair.  They should have you walk around barefoot.  Then they will bring you shoes.  Try on several pair.  Buy pair that fits nicely, feels good.  Run in them.  If they cause problems, go back to store.

In my humble opinion, the Zoots are not going to make one bit of difference to you.  You're better off buying a cheaper pair and running in them.
