Size: US Women’s 8.5 / EU 40 / UK 6.5 / JP 25.5 (men’s equivalent roughly US 7-7.5, but fits as women’s sizing—check On’s size guide if unsure).

Key Features:

• High-performance hard-court tennis shoe with carbon fiber Speedboard for energy return and propulsion.

• Engineered mesh for breathability and support.

• CloudTec outsole for cushioning and grip.

• Durable build favored by pros (worn by players like Iga Swiatek in similar models).

• Sleek, premium Federer-inspired design—great for tennis or streetwear.


gently used/pre-owned (some light dirt/marks on the outsole and upper, minor wear consistent with light court use or casual wear—no major rips, sole separation, or heavy scuffing). The mesh upper intact, CloudTec cushioning and Speedboard should still perform well. No box or original tags included.
