In reply to jaderosanne:
There's still a lot of snow about in the Aiguilles Rouges*, but I wouldn't bother with crampons - you'd be very unlucky to find anything frozen. Every time I've been up this season I've taken boots and a lightweight axe, but if I had any other sensible footwear short of B3s I'd probably not bother with boots either. The axe has definitely been useful, but you could also proably quite happily get away with just poles. Bit of a personal call - I don't often use poles and prefer to have an axe to hand any time I go near more than the odd patch of snow.
* - well, there was seven days ago but it's disappearing quickly.
