Look at the upper when choosing canvas shoes. Canvas shoes, as the name suggests, are usually made of canvas. When purchasing, it is necessary to see whether the upper curve of the upper is normal, whether the two shoes are symmetrical, whether there is any color difference; whether the stitching of the stitching at different parts of the upper is even and neat, whether there is broken thread, jump stitch; whether the color is consistent; from the heel Look at whether the shoe body and the sole are vertical, whether the lace hole is skewed, whether the left and right are facing the lining; whether the printed pattern and the text printed on the upper are clear, and whether the decorative icon pasted or stitched is firm.
Then check the soles. The sole is usually made of rubber outsole. This kind of sole needs to be wear-resistant, anti-slip, and lighter. Therefore, it is necessary to see whether the anti-slip stripes on the sole are clear when purchasing. There is no glue defect. Whether the stripe spacing is uniform, and whether the sole color of the same material is the same. See if there are any stomata or blistering.
Finally check the insole. The insole should be soft to the touch and have a certain elasticity. The printed trademark should be clear. Look at the rubber bonding parts to see if there are small glue spots and bubbles. Put the two shoes on the ground and check the color, pattern, height, length and width of each part.
