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

I've been a slip-on/off Kizik fan for years, and they served me well all over Italy last April.

What about a light weight hiker; something similar to a Merrill Moab? That class of shoe is gonna get you more stability and much more shock protection.

But feet, strides and body types are so individual so take specific shoe reqs with a grain of salt and .... don't leave on a trip without doing some miles wearing any new shoe.

I also have the Kiziks that Jay is talking about. They're not pretty, but they do feel so stable, unlike the less expensive Sketchers. I have not used them on a trip yet-I have some LL Bean tennis shoe type hiking shoes that I take on trips.

I learned about Oboz shoes on this forum and now own several pairs. You might put them on your "to try" list.

I haven't been on RS' Tuscany tour, but I have been on other tours where there are uneven surfaces like cobblestones or on trails.
You requested recommendations for shoes with "wide toe box and lots of stability and shock absorbance," which are my requirements too.
I take 2 pairs of shoes that meet your requirements: For stability I take a pair of Merrill hiking shoes in a pastel color and I also take a pair of Brooks Ghost (wide). I usually buy my shoes from Zappos especially if I need a wide width; free shipping and return.
Janet recommended Oboz shoes. I first learned about Oboz from Mardee and bought a waterproof pair for my Norway trip. Most comfortable shoes! Very cushiony!

Honestly, except for the orthopedic shoes I bought for work last year (I walk 15-18 miles a day delivering mail), which so far are the most comfortable and stable shoes I’ve ever worn, with a wide toe box, super spongy insole and pure rubber sole. Now, most of the other shoes, sandals, boots, I have I’ve purchased while on vacation in Italy because it’s much less expensive, and there are brands there that aren’t available in the USA, that make brands available in the USA look like they were made by children (which they probably were). Check out Geox shoes. Specifically their respira shoes which have breathable soles. I have their sandals and they’re literally the most comfortable sandals I’ve ever owned, and, as one who lived in sandals for the better part of 15 years, I’ve owned dozens of brands. Also, I bought them in 2022, when CONDOR AIR lost our luggage between Boston/Frankfurt/Milan, and the soles haven’t even worn out yet.

I love Hokas. They have a very wide toe box and are so comfortable. They are running shoes, so not stylish. The styles vary a lot, so I always need to try them on. I have the Challenger trail running shoes and the Graviota 6 (both have wide toe boxes).

I bought a pair of Salomon XT-6 recently, in salmon pink. They're quite an expensive shoe, but I got mine at a discount, presumably because they're pink and in a size 10. I've never had shoes with that level of support feeling before. My heels in particular feel very well supported, as I have quite narrow feet, and they're very comfortable. I like the drawstring fastening, which feels quite tough and hard wearing and lets you get them tight as you need to.
