Need recommendations for walking shoes for hot weather

I wear Pikolinos - shoes not sandals. I walk all over Europe with them and I have issues with my feet. They are way better then even using my orthotics in my tennis shoes.

Any shoe would work, skip any Gore-Tex as they would be warmer. Get SuperFeet insoles for any shoe you purchase to give you the best heel cup and arch support. you probably already have a good broken in pair of shoes you can use, just update them with SuperFeet insoles. Most shoes on the market do not have that great of support, although you can do Ecco or Vionic brands, which are known for better support for your feet.

Best suggestion would be to go to a real shoe store, where they measure your feet (sit and fit) and try on several different brands. Then wear them in your home (not outside) for a few hours and see how they feel on your feet.

I liked my allbirds in tree ( not wool)

Donna, i’ve never heard of Pikolinos so i found them on Zappos, but they don’t say anything about them (except material, weight, etc). I’m wondering why they’re better than others. They have some cute ones, like these…

I wear New Balance, love them and they’re half the price, but not as cute.
I’m tempted to buy the ones i linked.

You probably don't want an ankle boot, but the Pikolinos Vicar boot is a favorite of mine, literally wore them right out of the box for 12 days of heavy walking in the Baltics--lightweight but very supportive and well-made. On my recent trip to Rome and Budapest I tried another style of Eccos, the Street 720, a laced sneaker/oxford, and found them very light, supportive and comfy. I wear Smartwool low-profile socks and as long as the socks aren't super-cushioned my feet don't feel too hot.

Thank you for your replies. I definitively need arch support and my feet run narrow.
