Ivy Park x adidas UltraBoost 4.0 - Trainers - White - UK 4

This model is a collaboration between Beyoncé's Ivy Park brand and adidas, featuring unique design elements, branding, and a distinct white and gum colorway on top of the proven UltraBoost technology.

While the Boost midsole offers excellent cushioning, these are primarily lifestyle and light training trainers. For serious marathon running, dedicated performance running shoes are recommended.

The UK size 4 is a specific measurement. It's recommended to compare it with your usual shoe size or consult an adidas sizing chart. The Primeknit upper offers some flexibility, but the length and width are fixed.

It is not recommended to machine wash these trainers, as it can damage the materials and adhesives. Hand washing is the preferred method for cleaning.

The primary differences are the collaborative design elements, specific colorway (white with gum details), and exclusive Ivy Park branding, including a unique hang tag.

The rubber gum sole is designed for durability and provides good traction. However, like all rubber soles, it can show wear over time with consistent use, especially on abrasive surfaces.

No, the Primeknit upper is breathable but not waterproof. They are suitable for dry conditions and light moisture but not for heavy rain or puddles.

The Primeknit upper is designed to be snug. If initially tight, wear them around the house for short periods to allow them to stretch slightly to your foot's shape. Ensure you have the correct size; this is a UK 4.

Gum rubber can sometimes oxidize or pick up marks. Try cleaning gently with a damp cloth and a mild soap. For stubborn marks, a melamine eraser (magic eraser) can be used very cautiously on the gum parts only.

Yellowing of Boost material over time is a natural process due to oxidation and exposure to light. This does not typically affect performance. Regular cleaning can help maintain appearance.

Replace laces with standard flat trainer laces of a similar length. Many sports retailers offer replacement laces.
