Salomon
Aero Blaze 4 GRVL
A lighter, lower-stack sibling of the Aero Glide 4 GRVL, with Salomon's optiFOAM² midsole and a 2.5 mm-lug Gravel Contagrip outsole for pavements, gravel and hardpack. Reviewers found it lively and well-gripped on mixed surfaces but out of its depth in deep mud, wet rock and roots.
What's new: Moves to the newer optiFOAM² midsole with a 2.5 mm Gravel Contagrip outsole, quickLACE neo lacing, a more protective upper and extra reflectivity, at the same price as the Aero Blaze 3 GRVL.
About the Aero Blaze 4 GRVL
A gravel take on the Aero Blaze 4, the Aero Blaze 4 GRVL is what Salomon calls a lightweight running shoe that suits a run wherever it goes, with city parks listed as its home terrain. It is the lower partner to the Aero Glide 4 GRVL, at 37 mm in the heel against 41 mm, and shares its 8 mm drop.
The midsole is optiFOAM², Salomon's lightweight energy-returning foam. Underneath, a Gravel Contagrip outsole uses 2.5 mm chevron lugs for paths, gravel and hardpack. The engineered mesh upper uses sensiFIT construction and quickLACE neo lacing, with a moulded OrthoLite sockliner, and the shoe comes in a regular width only. An Aero Blaze 4 GRVL GORE-TEX version adds waterproofing for wet road-to-trail routes.

What it feels like
Fit
True to size
Trail and Kale found it true to size with a medium width and a reasonably roomy toe box, but RunRepeat's lab measured a narrow, tapered, low-volume forefoot that suits narrower feet, and there is no wide option.
