Balance training lowers the chance of another sprainStrong evidence
In 522 athletes aged 12 to 70 who had sprained an ankle, an 8-week home balance programme cut repeat sprains over a year from 33% to 22% (about 1 sprain prevented for every 9 people who did it). An overview of 46 reviews rates the evidence for neuromuscular (balance and control) training as moderate, and a Dutch guideline prefers supervised exercise to passive treatments, with surgery only if thorough exercise-based treatment fails.
These trials are mostly of athletes and about preventing another sprain, not about pain on walking, but they show an unstable ankle can be trained.

Braces and supports: strong for repeat sprains in sport, untested for walkingEmerging evidence
In 384 athletes, a semi-rigid brace worn for sport for a year cut repeat sprains to 15%, against 27% with 8 weeks of neuromuscular training, and the overview of reviews rates bracing as strong evidence for preventing repeats. After a severe sprain, in 584 people at 8 UK emergency departments, a 10-day below-knee cast gave a quicker recovery than a tubular bandage, an air-cushioned brace gave somewhat better ankle function at 3 months, a walking boot didn't help, and by 9 months there was no difference.
For everyday aches, the NHS suggests wrapping a bandage around your ankle for support, and Arthritis UK says a brace or support can help an arthritic ankle; the NHS's tendonitis page says take a support off before bed. No trial has tested a brace for ankle pain when walking. Using one on uneven ground while you rebuild your balance is our suggestion, extrapolated from the sport trials.

Shoes and insoles: advice, not trialsEmerging evidence
The NHS's advice for ankle pain is "wide comfortable shoes with a low heel and soft sole", soft insoles or heel pads, and no high heels or tight, pointy shoes. For ankle arthritis, Arthritis UK suggests a low heel, a wide front with about a 1 cm gap at the toe, thick cushioned soles, soft uppers and laces or straps, buying in the afternoon, and no ballet pumps or flip-flops; "A light but stiff walking boot can help ankle pain", and you may be able to have a rocker added to your own shoes ("Changes such as this often make walking easier"). Magnetic insoles were no better than ordinary cushioned ones.
For Achilles pain at the back of the heel, the AAOS suggests softer shoes or ones open at the back, and heel lifts. No trial has tested shoes, lacing or insoles for ankle pain when walking.

Keep walking, with the load adjustedStrong evidence
After a sprain, the NHS says keep moving once the pain allows, and NHS inform says reduce your activity for the first 24 to 48 hours, then try to use the leg more; early movement after a sprain has strong evidence, the overview of reviews found. While it's sore, the NHS says don't walk or stand for long periods.
In 38 people with Achilles tendon pain, carrying on with activity under a pain-monitoring rule did as well as 6 weeks of rest. So the plan changes how much you walk rather than whether you walk, except for one sore spot on a bone.

Exercise for each causeEmerging evidence
NHS inform's calf and ankle exercises (moving the ankle up and down and side to side, seated then standing heel raises, and a calf stretch) start with 2 to 3 repetitions little and often and build to 2 sets of 15. For Achilles pain, exercise alone helped most people in the long run. For ankle arthritis, Arthritis UK suggests strengthening on 2 or more days a week and 2.5 hours a week of moderate activity such as brisk walking, and a review says non-surgical treatment should be tried at any stage.
For impingement at the front, treatment starts with physiotherapy, strengthening, changes to activity and sometimes a brace. For the peroneal tendons, the evidence is case series and expert opinion, so the plan's strength-in-every-direction approach is our suggestion.

Medicines, injections and surgeryEmerging evidence
After a fresh sprain, anti-inflammatory painkillers have strong evidence, though the Dutch guideline urges care with them. For ankle arthritis, anti-inflammatories and injections give temporary relief; a fusion operation changes how you walk, and ankle replacements last about 10 years, Arthritis UK says. For Achilles pain, the AAOS considers surgery only after about 6 months of non-surgical treatment.
