Inov 8 seem to have very successfully gotten themsleves a brand that everyone recommends – often for good reason but they aren't the silver bullet.
There are stories of them falling apart, although I had a pair for about 3 years that didn't. They are a narrow fit though and they have minimal padding, which might be your thing, it might not.
The Salomons tend to be quite well padded, as is the Asics Tiburon (sp), it depends what you're after.
I went from my Inov 8 Mudrocs to Mizuno Wave Harrier 2s – I wanted something with a bit more cushioning yest still with a lightweight / thin sole. I tried on some Terroc 330s which were heavier and tighter around the foot compared to the Mizuno's. The Mizuno's are quite wide in the toe box.
Apparently the sole's on Walsh's wear out quickly.
