Best walking shoes with lots of stability

Feet are so individual it’s hard to recommend. What works for me might not work for you.

I also need a wide toe box because I wear CorrectToes toe spacers. I’ve transitioned to wearing only Altra brand and use the Lone Peak style for travel if I can find them in black. They are actually trail runners so have good grip. They are also mostly or close to Zero Drop so not sure if this will work for you.

I don’t need stability but their Torin style has more lateral stability than the Lone Peaks with a much stiffer heel counter. Last time I was purchasing waterproof shoes only the Torins were available in black so I went with them. They are really stiffer than I like but my foot will adjust after a bit to them.

I’ve not been on the Tuscany tour but have done Village Italy and Best of Italy wearing Altras.

As Pam says, it's hard to recommend a specific shoe since everyone has different feet and different needs. However there is an entire section devoted to travel shoes under the Tips and Trip Reports section of the website: https://community.ricksteves.com/travel-forum/best-travel-shoes

You could try SOLE BLISS leather sneakers with a side zipper. They are very spongy and comfy.
They are pricey but I get a lot of use out of mine and they look nice enough to go to a good restaurant.
I figured out to manage the zipper--you have to loosen the laces and then it's easy to close the zipper..

Hi Judie, I bought a pair of Abeo MXV Shift sneakers. They are the best walking shoes I have owned. Not only do they have a wide toe box, you can buy them with metatarsal support. After three neuroma surgeries and a broken foot my feet are a mess but these shoes are very comfortable and easy to break in. https://www.abeofootwear.com/products/abeo-mxv-shift-metatarsal-black-pink?variant=43998833180852
