Description

Technical Field

[0001] The utility model relates to a pair of roller skates, in particular to a pair of inline roller skates. Background Art

[0002] Roller skates can be broadly categorized as inline skates and double-row roller skates. Inline skates have four rollers arranged in a vertical row, making them easier to advance and faster than traditional double-row roller skates. However, the vertical arrangement of the rollers makes it difficult to maintain balance. Double-row roller skates have wheels at the four corners, providing greater stability and placing less strain on the ankles.

[0003] Inline skates are the mainstream of today's roller skate sports, whether for leisure, racing or fancy sports. However, inline skates are not suitable for beginners. If you want to buy double-row roller skates just to practice your sense of balance, it is easy to cause financial burden and waste. Utility Model Content
