1.Sole Cracking
The soles of high-quality safety shoes are typically formed by high-pressure injection molding, creating a sturdy sole unit with minimal air bubbles. Note the dual-density soles, usually made of two layers of PU - a durable outer layer providing good traction and durability, while a softer inner layer cushions and rebounds for the wearer's feet.
Our suggestion: Avoid purchasing shoes where the gripping layer of the sole is glued onto the comfort layer. This adhesive may wear off over time, leading to tread separation. Instead, opt for shoes where the sole is injection molded onto the upper, ensuring a stronger bond. Additionally, observe if there are air bubbles in the tread, indicating lower material density and poorer manufacturing processes.

2.Excessive Heat in Shoes
Quality footwear should keep feet at a comfortable temperature through insoles and liners, reducing moisture and odor through sweat-wicking capabilities.
Our suggestion: Pour a small amount of water on the insole. The water should be absorbed by the insole and quickly drawn away by the fabric. If there's foam forming on the insole, it won't absorb sweat, potentially leading to foot odor issues for your employees.

3.Loose Threads on Shoe
Upper Repeated folding of specific areas of the shoe upper during bending or stretching, as well as exposure to chemicals and materials in use, may cause the shoe's upper threads to fray. Choose shoes with double stitching and consistent thread size and spacing across the upper.
Our suggestion: Check for single stitching, inconsistencies, and cross-stitching, all signs of poor manufacturing. Bend the shoe; if there are stitches at or near the fold, these areas should be considered potential weak points.

4.Loss of Comfort after Prolonged Wear
As wear time increases, insoles may become compacted due to wear. If the shoe's comfort and rebound primarily reside in the sole unit itself, you shouldn't encounter any issues during use.
Our suggestion: Remove the insole from the shoe and see how comfortable it feels without it. This will give you a good indication of the shoe's long-term comfort. If it feels hard and uncomfortable without the insole, you might need to look for other options.

5.Upper Wear This is a common issue with shoe uppers made from cheap microfiber or so-called "action leather." Action leather uses only the middle part of the leather and covers it with a PU coating, which is not as high quality as full-grain leather.

Our suggestion: Choose shoe uppers made from full-grain leather or high-quality branded microfiber.
