I'm not going to give shoe brand recs, because honestly, I've found that it depends on the foot. (Like I'm the odd person out, because most running/walking shoes are the ones that give me the worst trouble. I wear VANS or Nike SB Chron, because for some reason skateboarding shoes work best on my feet. Really just depends on your feet and your gait, and everyone is so different.)
In any case, I have TERRIBLE feet problems and have my whole life, but here are a few of the things that help me on long park days:
1) Dr. Scholl's Massaging Gel Insoles (
https://www.amazon.com/Dr-Scholls-Comfort-Massaging-Insoles/dp/B01M9GSSJW) - available at many retailers, not just
amazon - I finally broke down, realized I'm no longer 18 years old (more like 40+) and got these for my shoes this summer and it was a GREAT choice. Last trip was two busy and very hot days in the park, and while my feet and legs were still a little sore, it wasn't even near what it would be without them. (Also, I normally would have a sore back and very sore calves after two full park days, but I didn't have either of those things after using the insoles).
2) Preheels Barefoot Scientist Blister Prevention Spray (
https://www.amazon.com/PREHEELS-Blister-Prevention-Innovation-Blisters/dp/B07N15HKWN) (I have also found this at Walmart) - Someone on here suggested this last year and OMG, it's GREAT. Has cut down on blisters and I even used it every day on a European vacation where I walked a lot and it's great. Pro-tip: Make sure it is fully DRY before you put on your socks and shoes, or anything else. Works great! (I also bring it with me and reapply if I change my socks/shoes during the day)
3) If you want double protection, use Body Glide Foot (AFTER the preheels spray is fully dry) (
https://www.amazon.com/BodyGlide-Foot-Anti-Blister-Balm/dp/B00115UN9Q) - this also works good by itself, but I prefer the spray if I only had one choice
4) Moisture wicking socks! Very important! I also bring a second pair with me and if I'm feeling like I need a refresh, change in the middle of the day.
5) Of course, bandaids and moleskin are also good to have in case you do develop a blister. SOME of the bandaids specifically for blisters work well, but also be wary. I used a brand I had never used before back on a August 2022 trip (I think it came from Walmart and was just like their store brand) and the adhesive got so glued to my skin, it was pulling my skin off. I literally had to soak my feet in the tub at my hotel so I could get the bandage off. DO NOT RECOMMEND.
6) I also agree with the people who said bring a second pair of shoes. I don't have to change my shoes much anymore because I do all of this and change socks mid-day if I need to for the blisters. But it's still good to have a second pair on hand in case you're feet start hating the first pair.
