I tried on this shoe in the store in a size 11 which was too tight and too short and a size 12 which was too loose. I have another pair of Sketchers (not this model) also without laces and size 11.5 is perfect. I don't know why these shoes are so loose. The insole is also very thick below the toe but not so much below the heel. However, the overall spongy feel on the soles does a great job of relieving hip pain. I think that's what they were made for, but that's what I bought them for. I would buy them again although I can replace the insole
