The worst thing about summer for me is footwear. Winter is great, I can live in boots; shoe boots, ankle boots, knee boots, even boots with a heel. Summer clothes are swishy and fun too.
But I literally don't know what to put on my feet in summer. I have truly awful circulation* so my feet swell during the day, made worse in hot weather. At weekends I can wear haivianas or trainers but the working week (office-based) is tricky. Any footwear that goes across the top of my foot (like ballerina pumps) makes me look puffy and any strappy sandals are trapping like a water balloon in a string vest.
Heels make the swelling worse too.
My mum had the same issue and went down the Hotter shoes route
