Our models typically wear US Size 2-4 or Australian Size 6-8, X-Small, Small, or One-Size garments.
On each product page, we provide the model's measurements and what size she is wearing to help guide you.
You can refer to the charts when selecting sizes but please note that sizes cannot be guaranteed and might vary slightly between brands.
If you need any advice about sizing, please feel free to drop us a line at: service@sunnoss.com
The measurements in the description of individual products are taken only across the front side of the garment, not around the circumference (e.g. chest and waist).
If you can't find a completely satisfactory size in our size chart, don't worry! Feel free to contact us anytime at service@irispetal.com or through our online customer service. Our team is more than happy to provide personalized advice, recommend alternative styles, or assist with customization needs. Your comfort is our top priority!

The R.A.D® UFO is a road-running super trainer built to develop speed across distance. Designed as a high-performance training tool rather than a race-day specialist, it blends advanced foam technology with geometry engineered for efficiency.
At its core sits SUPEFOAM™ - a dual-layer PEBA blend tuned for both cushioning and propulsion. The softer top layer absorbs impact and helps improve running economy by reducing fatigue over longer efforts. Beneath it, a firmer layer delivers structured energy return, creating a responsive catch-and-release sensation through toe-off.
A flowing rocker geometry works in harmony with a sculpted heel bevel to encourage smooth transitions and continuous forward momentum. The result is a ride that feels fluid at steady pace and controlled when picking things up for progression or threshold work.
Engineered for comfort without compromising performance, the UFO is well suited to long runs, sustained tempo efforts and structured training blocks where consistent quality matters. Purpose-built for the road - not the trail - it’s a precision instrument for runners focused on building speed the right way.
