adidas Adizero SL Reviews

At 175 lb and over 400 miles on their second pair, the Adizero SL is their most-used shoe: comfortable at any pace from warm-up to tempo, a 1:40 half marathon, and a tank of an outsole. The firm foam isn't good for slow recovery runs.

After about 150 miles, the Adizero SL is a great versatile travel shoe with barely any outsole wear and impressive grip; it's firm and stiff for easy runs and the laces needed replacing.

Bought the Adizero SL on sale for about $40 and finds it a good, durable daily trainer; some people call it firm but they didn't think it was too firm.

Moving from Hoka Rincons and Mach 4, the Adizero SL has been a really versatile trainer with a durable, grippy Continental sole.

An elite runner used them for about 100 miles as an all-round daily trainer, from easy runs and strides to moderate-pace efforts. They found the firm, light and snappy ride worked better than expected, and the outsole and upper held up well apart from some creasing and small cracks in the outsole ridges. They disliked the thick heel padding and thin tongue, which soak up sweat and stay damp between runs. They see it as a solid workhorse, especially for cross country and track runners.

About 30 miles on roads, wet paths and gravel, including a slow half marathon plus tempo and interval work. They liked the grip, stability and likely long life, and said it came alive at faster paces landing midfoot. They found the midsole very firm and lifeless at slow paces and on longer runs, and the fit snug, with a toe box that is not roomy and some numbness early on. They see it suiting short runs of around five miles for people who like a firm ride, with better rivals at the price.
