Help a runner out please

Been running for 1.5 years, but stopped now due to foot arch pain and lower leg pain. Physio said to strengthen it using foot exercise and stretching. She also recommended to switch shoes and use insole since I have flat foot and claw toes, which significantly impacts the energy absorption.

I have tried Nike, Puma and Adidas, but I didn't get good enough arch support and the toe box also felt cramped.

Please recommend good insoles or shoes for flat foot and claw toes. I wish to get back to running

P.S please help suggest a good smart band around Rs 5k. which has a reliable good heart rate monitor and GPS. Lost my old smartwatch during room shifting.

Thank you once again for your help everyone, cheers 🙏
