In reply to tjdodd:
> I replace mine when they are falling apart. Most shoes will soften over time (were yours saggy when you first bought them or have they just softened over time?). By climbing in softer shoes you will develop your technique and learn to be precise with foot work.
I've often seen that stated.... personally I am not convinced (shading towards thinking it's potentially detrimental rubbish). When I started climbing, a climbing shop sold me a pair of bulbous rubber clogs, marketed as suitable for beginers. It was a complete revelation when I purchased a pair of more precise shoes. Previously, I had been unable to use marginal footholds, so necessarily ignored them, it was only when I got decent shoes that my footwork started to develop. My view is that bad shoes can give too little feedback to learn efficiently.
If I was the OP, I would go to a shop, preferably one at a climbing wall, and try on a few pairs. If any seem to offer a significant improvement in precision and "feel", then upgrade. It might be the more expensive option, but think about the cost amortised across, say, a 6 month lifespan; what would you pay to be a better climber and improve faster for 6 months? That said, if "upgrades" do not seem appreciably better than your current shoes, then save your money - perhaps your feet are just suited to Simmonds.
