Description

Technical Field

[0001] The utility model is provided on sports equipment, in particular to an adjustable roller skate. Background Art

[0002] Roller skates first became popular in Western countries and were a popular fitness shoe in the early years. They have a very simple structure and come in two main types: four-wheel double-row and multi-wheel single-row. They are used by a wide range of roller skating enthusiasts. Different roller skates have different advantages and disadvantages. For example, single-row wheels are straight in the vertical direction, with a large contact surface, allowing the foot to tilt inward or outward significantly, making it easier to maintain balance and suitable for beginners. Double-row wheels only have four wheels on the ground at most times, meaning the soles of the feet are parallel to the ground. This makes the movements more difficult and requires a wide range of tricks. Therefore, it is important to have adjustable roller skates to suit a variety of users. Utility Model Content
