Way too small.
I ordered up a size figuring I could trim them to fit; I wear a US11.  The shoe in the picture is a UK10.5 which is about an US11-11.5. The insole is ok in the width (though just a tiny bit narrow in the forefoot) but fails miserably in length. 1/2" to 3/4" too short. Disappointing because the do feel like they'd be comfortable. Had to return. 😞
