I have faithfully worn my Allbirds through Scandinavia, Portugal, and several Adriatic countries. I am wondering if I would be better served - given the hiking - with a different shoe on the GAS tour?
I wore my Allbirds sneakers on the GAS tour in 2019 and they were great. Lightweight and washable. Also brought Merrells calf height rain boots since it was a Sept/Oct tour. Those were also good for the bit of snow we got in Switzerland. Brought dressy flats too, though I only wore them at the Mozart Concert Dinner in Salzburg. I wondered about hiking boots before that trip as well, but they were not needed.
I'd be wearing my Altras but that's just me.
I used low cut Merrill Moab’s , they have been my go to travel shoe for the last 6 years.
I am not familiar with Allbirds, but I think it's important to protect your ankles if you hike. Buy a good pair of hiking boots. The good ones last for a life time. The poor ones? Maybe a few years. Go to REI and try some on. Generally, the better (though more expensive) are made in Europe.
