I use a variety of sneakers for running, walking, hiking. Decided to try these because I liked them. For many years I have bought sneakers from different manufacturers in the twelfth size. These are the first to squeeze my legs so hard. I've done several walks for several miles. I hoped they would get better for my leg. Vain. Normal size 12 fits 12.5-13 of this shoe size. I expected them to be very soft on the heel. However, I have two pairs of other brands that match the heels much better.
