I've been a walker for 45 years and good shoes make such a difference! I was using a brand that unbeknownst to me caused me knee pain every day. Finally I switched shoes and pain is gone! This year I added some trekking poles and they are wonderful. (I had a month's episode of vertigo so felt these would be prudent to use in case a new onset occurs when walking). The poles are improving my posture, strengthening my arms and also using 45% more energy (i.e. burning more calories 🙂 If you haven't tried them yet, please do. I believe you will be very pleased with the results.
