I'm selling some foreign attire on my website. I would like to buy some adwords for say shoes and have it go to a subdirectory such as www.mysite.com/shoes and do the same with other things like say watches would go to www.mysite.com/watches and not go to my www.mysite.com directly. I would have better success if it went straight to the subdirectory. Is this possible does google allow it?

yes you can do that
