"I switched to Cage 3 from Asics Gel Resolution. My usual size is 10 but I had to get 10.5 to avoid toe bruise issue. It was comfortable and felt it is too big at times. When Cage 4 was released, I read that it runs big. I ordered my size (10) and it fits perfectly! The sock-like inner liner allowed my foot to fit snugly but putting them on is a challenge. I'm hoping it will get better over time. No break-in period needed. No comment on durability yet. So far, I'm loving this pair of shoes and may stock them up." via Nike
"This is an outstanding tennis shoe. It feels comfortable yet solid on the foot from the first try. The styling is best in class. The materials are high tech, yet the shoe retains a timeless classic look. I particularly like the lacing design that keeps the tongue in place. All in all, highly recommended..." via Nike
"Shoe fits snug and is very enveloping of the foot, hence providing great support." via Nike
