Our pick 
Saucony Endorphin Speed 4
82Score · Medium
from €125.99
A benchmark nylon-plated super-trainer: light, bouncy and genuinely do-it-all. With the Speed 5 out, the 4 is now a steal at German street prices.
Vivobarefoot Primus Lite III
76Score · High
from €115
The Vivobarefoot Primus Lite III is the reference barefoot gym shoe: a wafer-thin, zero-drop platform with class-leading ground feel that makes it superb for lifting, functional training and hard-floor work. It is polarizing though: the adaptation curve is real, versatility is limited, and the price is steep for what it is.
