The Duchess of Cambridge's shoe collection knows no limits. While many would do just about anything to switch wardrobes with the impeccably dressed royal, personally, I wouldn't know what to do with so many heels and the high probability of bleeding blisters. Kate must be superhuman, right? As someone who is almost always sporting a pair of thin high heels, we have to wonder if she's smiling through the pain in her arches or if she has the best heel hack known to mankind. Well, we may be retiring our trusty blister plasters for good because Kate has the hack to end all heel hacks. Back in 2015, Vanity Fair reported that the secret behind the Duchess's flawless high heel stroll is Alice Bow's leather insoles. The Insoles For High Heels (£15) were created to do the impossible: make any high heel — gasp — comfortable. Vanity Fair also reports that Kate has purchased "several pairs because she finds them so comfortable and the company told Royal Watch it has seen a 'massive surge' in sales, most likely in thanks to its new royal customer." With these insoles, Kate, who is expecting her third child, can continue wearing heels well into her pregnancy. And, looks like we'll be purchasing a bunch of these royal-approved insoles, too!
