adidas Adizero SL2 Reviews

Over 125 miles in them, with a longest run of 12 miles, and the midsole rated a standout: snappy, with good energy return, and versatile enough for easy runs, long runs, strides and tempo work. They found the upper durable and the shoe lightweight, and expect 300 to 400 miles from a pair. Downsides: the fit is snug and a bit narrow, so they suggest sizing up half a size, and they feel it is best up to about half-marathon distance.

Nathaniel Bailey found it firm-ish but peppy and very versatile, with standout wet traction and great value. The midfoot is narrow, stability is limited, and the thin laces are hard to untie.

A sleeper hit: the full-length Lightstrike Pro gives a smooth, snappy ride at $130. It runs narrow, one tester got a hot spot near his big toe, and there is no support for pronators.

At 157 lb the SL2 is super soft and well isolated as a daily trainer, though it runs narrow and slightly short.

With about 60 km in them, mixing easy runs, intervals and fartlek during marathon training, they found them comfortable, versatile and responsive when the pace picks up, with a padded ankle collar and a grippy, solid outsole. They would size up half a size, as the forefoot is not roomy, and the cushioning is plenty soft for most but not as soft as they personally like. Not an aggressive speed shoe, but a good one-shoe option for beginners and easy runs up to about 20 km.

Ten miles into the SL2, it's a good shoe; it's a bit narrow for their near-E-width feet, and relacing to skip eyelets made it more comfortable.

Two runners tested them, one with over 30 miles including a 12-mile run that finished at half-marathon pace. They liked the bouncy, smooth ride from the Lightstrike Pro core, the light feel, the snug race-like lockdown and the grip. Criticisms: the thick tongue and heavier mesh ran a little warm, one pair creased and irritated a toe, there is no stability, and they do not think it suits wider feet. They found it hard to beat for the price.
