Although it seems out of place for Union to sell Nike shoes again, but it fits perfectly to the store's lifestyle or high-end stuff...
I'm just going to paraphrase/quote a friend of mine about it - "It's better for Union to sell them because if it was at NikeTown, most consumers will not buy them due to it's price tag." ($385 for the shoes and I don't know how much are the bags and jackets).
(Here's a link to look at the whole collection: Highsnobiety - Nike x Tom Sachs NIKECraft Capsule Collection)
As you can see below, jackets and bags are more suitable for the customers of Union rather than NikeTown or maybe Nike Santa Monica.
