The biggest difference is in Patagonia the trail is often super muddy, very rocky, or totally wet. Sometimes there isn't really even a trail and you have to go by GPS.
Considering this, do you need hiking boots for Torres del Paine?
Good quality, broken in and waterproof hiking boots are your #1 essential item. From this unpleasant experience, it is essential that if you plan on trekking in Torres del Paine National Park (or anywhere else in Patagonia for that matter) you must – must – buy good quality hiking boots.
One may also ask, what shoes do you wear in Patagonia? I strongly suggest going for waterproof, at least ankle-high hiking boots meant for rocky terrain if you plan to hike while in Patagonia (and you should!) When hiking in the past, I've often just used the same shoes I would wear in the gym, but in Patagonia, I was glad every single day that I brought hiking boots.
Then, does Patagonia make hiking boots?

Are hiking boots really necessary?
The conclusion is rather simple: Hiking boots are not absolutely necessary, but unless you are going on a short and easy hike, it's highly recommended to wear shoes that are somewhat optimized for hiking. In the end, some people even hike barefoot. Strictly speaking nothing is absolutely necessary when hiking.
