Applications:

(1)Testing finished shoes for dynamic waterproof performance under walking simulation.

(2)Evaluation of outdoor footwear, sports shoes, hiking shoes, and casual shoes.

(3)Assessment of rubber boots, insulated winter footwear, and protective work shoes.

(4)Quality control in footwear manufacturing for water-resistant shoes.

(5)Research and development of new shoe materials with improved waterproofing.

(6)Verification of compliance with national and industry waterproof standards.

(7)Inspection of finished shoe prototypes for functional performance.

Product Information:

The Footwear Dynamic Waterproof Tester is designed to evaluate the waterproof performance of finished shoes under dynamic, flexing conditions. By simulating walking and repeated bending in a controlled water environment, the instrument measures either the number of cycles until water penetration occurs or the area of water ingress after a set number of cycles. This allows for a realistic assessment of footwear permeability and waterproof resistance.

Product Features

(1)Simulates walking flex with adjustable bending angles and speeds.

(2)Measures dynamic waterproof performance quantitatively, based on cycles to water penetration or penetration area.

(3)Multiple testing stations to allow simultaneous testing of a pair of shoes.

(4)Integrated counter tracks the number of flexing cycles accurately.

(5)Adjustable zigzag angle (5–60°) to match different shoe types.

(6)Variable zigzag speed (5–150 cycles/min) for diverse testing requirements.

(7)Durable construction suitable for wet testing environments.

(8)Touch screen interface for cycle counting and parameter setting.

(9)Water tank with controlled depth and dyed water for clear visualization of water penetration.

(10)Compatible with various types of finished footwear, including sports, casual, and protective shoes.

Technical Parameters

Accessories

(1)Water tank with dyed water.

(2)Sample shoe holders/clamps.

(3)Touch screen controller.

(4)User manual and calibration certificate.

Test Procedures

(1)Install the finished shoes on the shoe holders/clamps in the water tank.

(2)Set the desired zigzag angle and flexing speed on the touch screen interface.

(3)Fill the tank with water to the required depth and add dye for penetration visualization.

(4)Start the test, allowing the zigzag mechanism to flex the shoes repeatedly.

(5)Monitor the shoes for water ingress; the system records the number of cycles until penetration or measures the penetration area after a preset number of cycles.

(6)After completion, remove the shoes and analyze waterproof performance according to the standard.

Maintenance Information

(1)Clean the water tank and shoe holders after each test to prevent residue buildup.

(2)Regularly inspect the zigzag mechanism and clamps for wear or misalignment.

(3)Check the touch screen and counter system for proper function.

(4)Drain and replace water regularly to maintain testing consistency.

(5)Store the equipment in a dry environment when not in use to prevent corrosion.
