Aero Glide 4

Yes, it fits true to size for most runners, so order your usual running shoe size. Salomon's last runs slightly snug through the midfoot compared with roomier American brands, so if you have a wider foot or are between sizes, consider going up a half size. The forefoot gives your toes room to splay on long runs, but the overall fit is secure and performance-leaning rather than relaxed.

It is well suited to long runs and the high-mileage weeks of marathon training. The deep 43.2mm heel stack keeps your legs fresh and takes the sting out of hard pavement, which is exactly what you want on steady long efforts. It is not a race-day shoe, since it has no plate and is not built for speed, but as a cushioned trainer to bank comfortable marathon-training miles it is a strong choice.

Yes, it is a sensible beginner shoe if you are a neutral runner. The soft, protective cushioning is forgiving on new legs and joints, the high drop suits heel-strikers, and the planted platform feels stable and confidence-inspiring. The only caveat is fit: Salomon runs a little snug, so beginners with wider feet should try before they buy or size up a half. For easy runs while you build fitness, it is a comfortable, dependable option.

Both are neutral max-cushion daily trainers built for comfort. The Saucony Triumph 23 fits more generously with a roomier toe box and tends to feel a touch more energetic underfoot, while the Aero Glide 4 has a higher drop and a snugger, more secure Salomon fit. If you want a roomier fit, go Saucony. If you like a high drop, a locked-in feel and a planted ride, the Salomon is the pick.

Durability is a strong point, in line with Salomon's reputation for hard-wearing build. The upper is well finished with no weak points that tend to fray, and the outsole rubber holds up well to road miles. As a daily trainer built for high mileage, you can reasonably expect it to see out a normal shoe's life of steady road running before the midsole softens off. It is a shoe built to take a beating on the roads.
