Now that it is finally summer (albeit a slightly less intense one than it was three days ago), I think we’re all entitled to carry around our summer SOS kit. 

I’ll deal with the superficialities first. In the heat, a dress is the only sensible option – although not a tight Melania one. Cotton shirt-waisters – airy around the legs, but with decent coverage of the shoulders and upper arms – are the way forward in the office. 

Next up, a backpack: when it’s really hot, hand-held bags become sweaty and cumbersome. Besides which, you need room for spare shoes and the rest of your SOS kit. A bottle of water and a face spritzer to help hydrate skin and keep it cool – especially if you can keep it chilled in the fridge.

The main thing, though, for summer contentment, is happy feet and swell-free legs. There’s no single universal cure for the latter. Diosmin Plus (£26 for 60 capsules) is a supplement for the longer term; Legs in the Air (£10 for 50ml) is a good little topical weapon to have close to hand while, magnesium flakes (£9.95) will help take down swelling (all from victoriashealth.com). Drinking lots of water – so boring – helps, too.

Comfortable shoes are key. Suede – impractical in the rain and generally avoided by Brits for that reason – is actually perfect in summer, as it’s softer and more giving than leather. These, from Office, are fashionable, flattering and comfortable. A pair of Adidas gazelles (and cotton socks) are a useful stand-by and come in great colours. 

Finally, if all else fails, you should always have Compeed’s Anti-Blister stick to hand (£4.25 from Boots) – and Margaret Dabbs’s footfile (£24). I’m not kidding. You never know when your heels will turn Liz Hurley on you. And Dabbs’s file is the best I’ve tried. Not the most poetic additions to a bag, but eminently better than mangled feet.
