Only used once- ended up being too big and narrow for me. These have super stiff carbon soles and a unique upper to limit flex for better power transfer. Double and bi directional Boas for a super dialed for. Retails for $500, asking $100 OBO.

For sizing I wear a women’s 6.5 or 7 and have a little bit bigger volume foot so I’d recommend someone like size 7-8 with a narrow foot.
