Looking for a pair of good running shoes for less than $100? Keep looking. Among the four new shoes reviewed by L.A. Times gear guy Roy Wallack, the cheapest pair came in at $120. And you thought running was the inexpensive exercise. Wallack had the fewest (none) dislikes for the Adidas Energy Boost ($150), “a lightweight shoe with foam midsoles composed of hundreds of capsules of expanded TPU (thermoplastic polyurethane).” He also liked the On CloudRacer ($129), with something called “Cloud-Tec” shock absorption, actually 13 half-circles of rubber on the sole that compress and quickly return to form, although he advises removing the 2-inch oval bump on the removable foot bed. For minimalist runners, Wallack recommends the New Balance Minimus Hi-Rez, a 4.5 ounce super-flexible sock-shoe that sells for $120. Finally, Wallack reviews the ultralight Nike Flyknit Racer, whose $160 price tag, he says, is twice what it should be. Read all of what Wallack likes and doesn’t like about the shoes.
