MODEL COMPARISON · RUNNINGAREA EDITORIAL · 31 OCTOBER 2026
BIOSPEED 5 PRO and MEGA3 PRO both carry the 361° name and the PRO suffix. Their manufacturer descriptions identify different foams and different support structures. Those details are more useful for identifying the models than treating PRO as a shared construction standard.
Compare the named components
| Model | Family reference | Midsole name | Support description |
|---|---|---|---|
| BIOSPEED 5 PRO | 672612201 | CQT FLAME / TPEEP | 2+7 hybrid carbon–fibreglass plate |
| MEGA3 PRO | 672632225F | CQT EXTREME | QU!K BALANCE midfoot nylon anti-torsion plate |
These entries follow the BIOSPEED 5 PRO Apex and MEGA3 PRO Ultramarine pages linked below. They describe components; they do not give us a common measurement of plate stiffness or establish which shoe is faster for a particular runner.
What the BIOSPEED hybrid label tells us
361° calls the BIOSPEED 5 PRO structure a 2+7 hybrid carbon–fibreglass plate. We retain that wording as a model-specific label. The page does not define it as a material percentage or provide enough manufacturing detail to reconstruct a layer schedule, so we do not turn the two numbers into either of those claims.
The same page names a zoned RPU outsole and a woven upper. When comparing listings, check those fields alongside the support description. A plate label alone leaves out other parts of the product you are buying.
Why we keep the MEGA3 description separate
The MEGA3 PRO page identifies its nylon component at the midfoot and describes it as an anti-torsion structure. That is more specific than saying the shoe has no support plate, and different from giving it the BIOSPEED hybrid label.
Our MEGA3 PRO support guide discusses that wording in more detail. Here, the practical point is to keep each component name attached to its own model. Neither the shared brand nor the shared suffix justifies copying a material description across.
Make the comparison in separate steps
First identify the model family, then compare the disclosed components. After that, inspect the photographs for the colour you want and read the complete size label. The BIOSPEED 5 PRO listing and MEGA3 PRO listing keep those checks together without combining the two products into one set of specifications.
The manufacturer chart distinguishes US Men from US Women. Our selectors also show EU, UK and Brand CM where verified for the exact model. Brand CM is not our measurement of internal shoe length; the size guide explains what information to include in a sizing enquiry.
This is a comparison of published construction, not a RunningArea wear test. We have not run a controlled comparison of the two shoes, so we do not assign a pace range, an efficiency advantage or a stiffness ranking from these descriptions. The evidence supports a clear distinction between their named components; fit and comparative running performance remain separate questions.
