Salomon S/Lab Phantasm 2

A genuine super shoe with a great PEBA midsole feel, but the narrow unstable heel and half-size-long fit make it a pass at $275 — the reviewer would only consider it after sizing down a half size, and even then would not recommend it for runners with any pronation or stability needs. — Doctors of Running

A genuine super shoe with a great PEBA midsole feel, but the narrow unstable heel and half-size-long fit make it a pass at $275 — the reviewer would only consider it after sizing down a half size, and even then would not recommend it for runners with any pronation or stability needs.

Best for: Neutral runners with stable mechanics who can size down a half size; marathon racing for those who don't need stability.
