Doubles of pages in hikashop SEO

Hi,
How can i delete doubles of pages in hikashop, or make 301 redirect for the product and categories pages?
What i mean:
For example:
I made category with items
in hikashop this product page will be
if i click

and

index.php/spetcodezhda/category/1212-tkan

if i click direct like:

It will have url adress
index.php/spetcodezhda/tkani/product/listing

How can i make ONE page with one url adress, without doubles?

I just want to say that i have 2 same pages with different urls.
The google and yandex finders will include my pages with problems couse it is 2 same pages
It is for SEO
Thanks,
Best regards, Artem

PS I know how it make on k2, virtuemart and flexicontent, but i don't know in hikashop(

i understood,
it is very easy, if i block this urls in the robots!))) Very easy
