This will be fairly short and sweet, the Miuras are pretty much rock shoe perfection!

For bouldering, sport and trad they are fantastic. I have owned a pair of velcros for a year and used a pair of lace ups regularly. They are the only shoes i have found that are comfortable enough to wear for long periods but still being technical enough for hard routes. This means you only need one pair of shoes whether your doing severes or E numbers. I use and abuse mine every week, nearly every day in fact and they are yet to get soft, or damaged, so they are very durable.

As with all shoes they are pretty subjective, so they might not fit you as perfectly, or be as comfortable for long days as they are for me. I can assure however on the durability and quality of these shoes. They dont stretch at all, which i guess could be a pro and a con, so be warned!
