How are inventory levels these days ? Worth an hours drive?

I would say so. Depends on what you're looking for.

Yes. Wide selection at every shoe store I was at

It can be worth it. It would depend upon how specific of an item you are looking for. There are other stores within that carry items of multiple specific brand outlets that you wouldn't expect to see. For example, Vans and other outlets. Just go there. It will be fine.

Yes. Visit Adidas and Nike Store. Plenty of stock items.

Same like other outlets. Yes and there's also mall probably 20 minutes away if you don't find what you like 😉
