Footner CoolActive Massager
This is designed for people who spend a lot of time on their feet – but we'll be carrying it around to instantly cool feet that are hot and swollen. (One of the downsides – and there aren't many – of summer.) The Footner CoolActive Massager is really clever. (Once you've figured out how to use it, that is! Took us a minute or two.) Basically, you depress the metal rollerball on the foot, and it dispenses a cold, soothing foam with a hiss!!!! And we're talking cold. Not ice-cube-cold, but very cooling indeed. The rollerball itself can be used to glide the product over the foot, while helping to physically disperse puffiness.
It's great for feet that have just done a long run, after wearing heels for a long time – or just from traipsing city pavements, which we do a lot of in our quest to notch up 10,000 steps a day.
Bottom line: very cool. Literally.
PS One warning: it's strictly an aerosol – so do check out cabin baggage security guidelines before stowing it in your little plastic Ziplock bag.
