Adidas Ultra Boost 23 Shoes

Description

• Upper: High-containment Primeknit+ upper that adapts to forefoot swelling and bunions, supported by a molded heel counter to keep the calcaneus bone aligned.

• Midsole Cushioning: Ultra-dense Light BOOST foam stack engineered to dissipate heavy vertical landing forces and reduce shock loads on knees, ankles, and hips.

• Cushioning & Stability Technologies: Integrated L.E.P. torsion plate prevents excessive arch collapse under body weight while maintaining a smooth forward roll.

• Outsole: Broad, full-contact Continental™ Rubber footprint mapped to eliminate localized pressure spikes under the heel and metatarsal heads.

  Key Features & Benefits

• Joint Shock Mitigation: Light BOOST foam buffers continuous surface strikes to lower impact stress on ankles, knees, and lower back joints.

• L.E.P. Arch Support: Embedded midfoot shank stabilizes the foot’s natural roll, reducing tension along the plantar fascia band.

• Grounded Rearfoot Lockout: Molded heel clip cradles the rearfoot to maintain proper anatomical alignment from landing to toe-off.

• Removable Footbed: Factory sockliner removes easily to accommodate custom medical orthotics or high-arch support insoles.

  Sizing & Fit Advice

  Fits True to Size (TTS). The removable sockliner easily accommodates low-profile custom orthotics; select half a size up if using thick custom inserts.

How to Find Your Size (Step-by-Step Guide)

1. Setup: Place a plain sheet of paper on a hard floor, flushed against a flat wall. 2. Position: Stand on the paper with your heel resting gently against the wall (wearing your preferred athletic socks). 3. Mark: Mark the furthest point of your longest toe on the paper with a pencil. 4. Measure: Measure the distance from the edge of the paper (wall) to your mark in Centimeters (CM).

Recommended Fitting Margin:

• Casual / Lifestyle Wear (e.g., Samba, Gazelle, Stan Smith): Add +0.5 cm to your measured foot length.

• Performance Running / Athletics (e.g., Ultraboost, Adizero): Add +0.5 cm to +1.0 cm for comfortable movement and toe clearance during long runs.

Adidas Signature Fit & Characteristics

Fractional EU Sizing System: Adidas uses a unique fractional European sizing system. Always rely on your foot measurement in CM for exact sizing match.

Fit Profile: Classic heritage models (Samba, Gazelle, Campus) tend to have a sleeker, slightly narrow profile, while performance models featuring Boost or Lightstrike foam provide an adaptive, locked-in wrap around the midfoot.
