What are the most comfortable women’s sneakers?

Hey guys. What are the most comfortable womans sneakers for walking all day? Getting desperate as im going on a week long walking tour soon and can’t find anything that doesn’t hurt after a couple hours. Ive tried expensive Ascis and Hoka which are very comfortable for short walks but become very painful for long walks. Tried thick socks and various insoles too. Thank you. I think I have plantar fasciitis as I get heel pain. I also get heat blisters on the bottom of my feet at the front. I’ll be hiking in a national park so would need good grip too.
