Advice on cv boot please

[jimmy2007]

Hi, at last mot I was shown both cv boots cracking but not leaking yet and was told to keep an eye on them.
In the 8 years I had my Passat I already changed the nearside twice and the offside 3 times.
Can anyone suggest a brand that is going to last?
I saw on wheeler dealers Ed China using blue rubber very soft ones that are apparently long lasting but can't find anything of that sort.
Can you please point me in the right direction?
Thanks
