How about some La Sportiva Katanas?
I'm a big fan velcro shoes, so although the Miuras are great shoes, I'd want something that comes on an off more easily.

the Anasazi lace ups are hands down the best shoe I've ever had.

I've had a couple sets of lace ups, currently have the Miura VS, which are great, had the lace up Miuras before these, guarantee the laces will break in those. Velcro shoes are fine, I was skeptical too. My next set of shoes will probly be a set of Mythos, but not because of the closure system, just looking for a slightly more comfortable shoe.

What is "the next level"?

What's wrong with the Defy? If I had to only have one model of shoe, that would be it.

A soft comfortable shoe that edges and climbs cracks and sport.

Get a Pontas, it's more precise and edges a little better. You should probably get a Defy and Pontas, and only put the Pontas on for harder routes.

The next shoe you get should be the one that fits your foot shape the best. Every big climbing shoe company makes a model that is good for "mostly bouldering with some periods of sport climbing in between. It will depend on things like, is your foot wide or narrow. Low arch or high arch. Long toes or short toes. All of these variables effect shoe fitting. If you have a wide front foot with a lower arch usually that means a five ten shoe will work well (like the anasazi velcro or the verde) if you have a narrow foot with a high arch try the sportiva miura vs or the testarossa. the optimus prime fits a lot of foot shapes well, but make sure and size it near your street size or it will not do what it was made to do. most people size that shoe too small. or if you have a really wide foot or long toes try the acopa merlin. it's an excellent all leather aggressive shoe. bottom line, go to a good climbing shop and put your feet into the shoes. i've had lots of models that i wanted to have work for my foot shape but didn't. don't settle for a poor fitting shoe.

what would you recommend for a really,really wide forefoot, with very short toes, and a low arch?

sorry Mr Nelson

Wow, were you on the floor kicking and crying when you wrote that?

If you tried the Miuras, and they fit, what's the problem? Fit in a climbing shoe is obviously important; I'd not buy shoes over the internet without trying them on first. So, again, if the Miura fits and you like it, what's the problem? It's a fine shoe for pretty much everything - unfortunately, it doesn't fit me.

I'm not trying to be a jerk here, but I think climbing shoes are too personal to expect a decent response to this question. Go try them all on, talk to the guy at the gear shop, and decide which ones you like the best. It's as simple as that.
