Suggestions on dealing with duplicate content?

[punchseo]

What are the best ways to protect / deal with duplicate content? I've added an example scenario,

• Nike Trainer model 1 – has an overview page that also links to a sub-page about cushioning, one about Gore-Tex and one about breathability.
• Nike Trainer model 2,3,4,5 – have an overview page that also links to sub-pages page about cushioning , Gore-Tex and breathability.

In each of the sub-pages the URL is a child of the parent so a distinct page from each other e.g.

• /nike-trainer/model-1/gore-tex
• /nike-trainer/model-2/gore-tex.

There is some differences in material composition, some different images and of course the product name is referred multiple times. This makes the page in the region of 80% unique.

Any suggestions welcome about the above example or any other ways you guys know of dealing with duplicate content.

So the issue is that you have sub-pages which contain a lot of the same information about cushioning, Gore-Tex etc?

If the content is reasonably unique, then it's a case of optimising each sub page for 'trainer model name cushioning' or 'trainer model name Gore-Tex' as appropriate.

Alternatively, you could create one high level glossary page for all the terms used for all the trainers, and then canonicalise each sub page to that one - then you won't risk the duplicate content filter, and provide a useful resource for people who might be looking for Gore Tex Trainers, rather than Nike Model One With Gore-Tex Trainers...
