Tools I use

Following the example of Daniel Paleka, here are some tools I use:

Travel Gear:

I like travelling light, especially when spending a few months living out of a backpack. My setup is now pretty decent, with an old 44L Osprey Talon hiking pack (it's not ultralight but at 1.2kg empty it's not far), and a vintage patagonia waterproof backpack I use as a computer bag, plus a few essentials.

This works as a carry on setup in most airlines (patagonia bag fits under seat, Osprey in top compartment). Total weight of setup is 12kg, which includes a 2.2kg laptop, 2 phones, and clothing down to ~0C. It might be possible to fit everything in the Osprey, but I prefer the flexibility - Neither bag is fully stuffed, which means I have room for snacks if I expect to be in less grocery friendly places.

To get down to this weight, I mostly had to bring technical clothing (nicer looking Colombia hiking pants) and no jeans. A good Decathalon rain coat has been helpful a few times, and serves as the wind blocking layer above a fleece.

Most random but useful item: TSA approved scissors. Seems dumb, but I've been glad to have these more than a few times. Also, laundry mesh bags have been great.

Shoes:

My friend (who hikes a lot, recently doing the 3000km NZ trail) got me into "barefoot" shoes. I started with Vivo Primus Lites back in 2022, and found them too thin for daily city walking. A year later, I got the Xero HFS ii in black, and found them to be great - good enough for a 3 day trek in the Dolomites, though they did chip a bit on the rocks. They have more padding than the Vivos, but are still very thin. For even more padding, I recommend Lems, but the shape didnt work for me. For hiking, I got the Xero Scrambler Mid 2 - non waterproof, as that is what was in stock. I think they are great, though i'd probably get the waterproof ones. They look nice enough to be the only pair I take travelling, and have good grip and padding.

Barefoot shoes are a bit of pseudoscience - there are some studies showing they help even in running in mitigating knee impacts, but I know they did solve my arch flattening over time. I'd sometimes have heel strikes in the city, but with the xeros that's almost gone now. What helped a bit was videos from Chase Mountains, who is a big "minimalist shoe" advocate. Who knows, maybe in a few years I will find that I did some damage - but so far I think it was a good bet, as long as I keep doing strength and balance exercises.
