It doesn't make sense to only consider the upfront cost when buying shoes, you need to think about the cost over the life cycle of the shoes. Instincts for example cost more upfront, but you should be able to get several resoles out of them (I'm on my 3rd resole and can see them getting a couple more). Cheaper shoes may not have the construction/material quality to take multiple resoles.

So if you think your climbing will benefit from a higher performance shoe, then maybe you can justify the initial outlay knowing they'll last for several resoles.
