DESCRIPTION

Undercover Jay Yoon 58/92A/88A, 4-pack is an aggressive inline skate wheel concept developed around functional asymmetry, allowing skaters to fine-tune grind performance and rolling behaviour within a single setup. Designed for technical street and park skating, this wheel set reflects a clear understanding of how durometer placement directly affects control, durability, and consistency during grinds. The 58 mm diameter provides a compact, responsive feel that supports fast spin-up, precise foot placement, and confident lock-ins on ledges and rails. What defines this wheel set is the mixed hardness configuration: two wheels feature an 88A durometer for grip, vibration damping, and controlled rolling, while the two 92A wheels are intended specifically for the inside position. The harder 92A urethane significantly reduces friction against ledges and coping, helping to minimize wheelbite during grinds and maintain speed and stability when locked in. This targeted hardness placement allows skaters to push harder into grinds without unwanted drag or hang-ups, while still benefiting from the smoother ride characteristics of the softer outer wheels. Manufactured from Undercover’s high-performance polyurethane, the wheels offer strong abrasion resistance and consistent rebound, even under repeated impacts and lateral stress typical of aggressive skating. The core construction is optimized to support the urethane under heavy load, maintaining shape integrity and predictable performance throughout longer sessions. The Undercover Jay Yoon 58/92A/88A wheel set is engineered for skaters who understand the importance of wheel positioning and want a setup that actively supports grinding technique, speed control, and durability in demanding urban environments.

Sizing advice for inline skates

FIND YOUR SKATE SIZE

For the best performance, inline skates should have a snug fit. It's not necessary to buy inline skates one size larger than your foot size; as they break in, all inline skates will expand and widen over time. It's important to know that soft boots will expand more than hybrid or carbon boots.

3 EASY STEPS TO MEASURE YOUR FEET:

Step 1

Place and fix an A4 sheet of paper on the floor against a straight wall that ends flush with the floor. Wear your usual skating socks for more accuracy and place your foot on the sheet with your heel touching the wall (make sure your heel touches the wall without significant pressure.)

Step 2

Stand relaxed on the foot you are measuring and draw a line around the outline of your foot starting at the big toe. Be sure to hold the pencil vertically to prevent any deviation. It's ideal to have a friend draw the line for better accuracy. Measure the length of the paper to the line: that's your MONDOPOINT size.

TIP: For the best fit, measure your foot after a short skating session or at the end of the day as your foot will naturally swell and expand.

Step 3

Do the same for the other foot and compare measurements. The correct size will be the length of the longer foot:
Precision fit add 2-3mm.
Comfort fit add 4-6mm.

Now, with these measurements, you can take the correct size from our sizing charts.
