What do you do when your reliable pair of flats is getting a little worn on the inside, but you’re too attached to them to get new ones? Spice them up with some DIY shoe inserts, of course! These Easy Sherpa Shoe Inserts from Me Sew Crazy are just the thing to transform a simple flat shoe into something toasty for the last few weeks of winter. (There’s still snow on the ground where I live, so no shoe is too warm for this gal!) This is also a great way to add a little more support to a stiff shoe, and the inserts are so soft—it’s like slippers you can wear outside!
