How it performs
Comfort and fit
The upper is widely praised, with top-rated ventilation; the fit is bulkier than earlier Speeds.
Durability
Toebox rated 2/5 — better than several rivals but still a soft spot.
Value
Contested. Lab testing rates it superb; Running Shoes Guru scores it 7.0 and says it feels slower than version 4.
Breathability
A perfect 5/5 in lab testing.
Flexibility and responsiveness
73.2% heel and 78.2% forefoot energy return, aided by a nylon plate that stays flexible rather than rigid.
