Wanting some new shoes and was told these are very good and comfortable the decription for them says with a thermo-forming upper for a perfect custom fit. Heat sensitive material is infused in the shoe upper, the shoe is heated in a special oven. Vacuum Form: While Heated the shoe worn, wrapped and sealed in a vacuum device that withdraws the air. The shoe instantly conforms to the foot. Cool: The upper is left to cool and perfectly retains the shape of your foot for a glove like fit. I'm confused how can you by these online if they're custom fit?
