Size Guide

Deck Sizing

Choose deck width based on your style, terrain, and shoe size.
Length and wheelbase vary by shape; width is the key starting point.

Deck Width Best For Notes
7.5″ – 7.8″ Youth, smaller riders Lighter, quicker flips; less foot space.
8.0″ - 8.125" All-around street/park Great starting point for most skaters.
8.25" – 8.3″ Street & park balance More landing room; still flicks well.
8.5″ - 8.75 Park, bowls, transition Extra stability and control at speed.
9.0" + Vert, cruise, bigger feet, Swampy Stable ride; flips feel heavier.

Shoe size tip: US Men’s 6–8 ≈ 7.75–8.0″ • 9–11 ≈ 8.0–8.5″ • 11.5+ ≈ 8.5″+. Preference varies.

Truck Sizing

For best performance, match truck axle width to deck width.
Sizing Labels vary by brand—use this as a quick reference.

*Size names differ slightly by brand/series—check each product page for exact fit.

Wheel Sizing

Pick diameter for terrain/speed and durometer for hardness/grip.

Diameter Use Ride Feel
50–53 mm Tech street, smooth parks Quick pop & flip; least speed over cracks.
52–54 mm All-around street/park Balanced speed/control; most popular.
54–56 mm Park, bowls, small transition More roll speed; stable landings.
56–60+ mm Rough streets, cruiser, big transition Faster over cracks; heavier feel.
  • Durometer: 99A = classic street; 101A = harder/faster (smooth parks); 78A–87A = soft/cruiser/rough ground.
  • Contact patch: Wider = more grip/stability; narrower = easier slides.
  • Wheelbite tip: Bigger wheels may need risers and/or firmer bushings.

Clothing Sizing

Clothing sizes vary by manufacturer/brand. For the most accurate fit, please refer to the Size Guide on each product page—measurements are provided per brand and style.

      V1 Shape

      Coming in two Sizes:
      52mm & 54mm

      Great looking graphic with an orange & red background that has some wolverine style blades cutting through!

      X-Formula rolls over rough terrain like softer wheels do, but slides much like a harder wheel will.

      Speed: X-Formula™ is extremely fast because it has a super high rebound. X-Formula rolls much smoother and faster on all terrains because it absorbs vibration and softens impacts much better than any other wheel in the market.

      Grip & Slide: The slide-ability comes from its unique blend of high performance materials. X-Formula will slide when you ask it to, and grip when you need it most. This is because X-Formula is specially formulated for any terrain. It has been developed over a ten year period to optimize performance and fine tuned to perfection. X-Formula is very unique product

      Durability: X- Formula™ is smooth, fast and durable. It has been developed using the highest quality, longest lasting materials. X-Formula is a great value and because it softens landings and absorbs vibration, it is also better on your body which can add longevity to your normal day of skating. These wheels will change your life!
