Hi dear...You are nevertheless a very active person despite the injury that great!!! Well ice can help sooth...but considering your age, I would say repeated applications of ice, wil actually clog the blood supply to both your feet . Rather i would encourage you to apply modest heat, continue to wear the soft foot wear you are already wearing and continue the walks.....the best way to beat arthritis are to keep using those joints gently by walking....soaking your foot in warm water with a little salt or placing warm towels can rejuvenate your tired foot... Have a modest balanced diet with lots of fruits and water ...rather than taking multivitamin pills. And do keep your Blood pressure and sugar levels in check . As this can otherwise affect your foot and walking... I hope this answers your query dear. Take care
