my advice - 1 size smaller (EU 37,5)

the ultra-neon laces and soles are simply amazing

• Engineering mesh: compromises the top, providing lightweight breathability.
  

• FlexiFilm - offers unsewn overlays that improve fit and feel.

• RunDry Lining - Removes moisture to provide the user with smooth, dry and comfortable operation.

• PowerGrid Midsole – Offers a highly padded ride throughout the cycle of travel.

• Tri-Flex - Provides more ground contact and optimal toe flexibility.
• The Swerve has added underfoot cushioning?but no added weight. This plush cushioning plus the barely-there upper fit makes the Swerve ideal for a smooth, comfortable run.
