The Nike Lunarglide+ 4 is not all about light weight. If you loved the comfort, ride and stability offered by the past models, you will be blown away by the latest one. The shoe comes with a completely new sole design for more support. It is almost 10 percent lighter than the + 3 shoe. You will also notice the neat midfoot support system and the single layered engineered mesh. The shoe has made a great first impression on me, although I must add a disclaimer that I haven’t used the shoe long enough to tell you how durable and stable it will be over time.
Nike Lunarglides have always been known for their support. It has been designed to fit a diverse group of runners with wide range of gait patterns. The dual density midsole of Nike Lunarglide+ 3 with its soft and firm foam combination consists of a soft midsole foam, or Lunarlon, inside the angled, firmer foam cavity. It offered great support, motion control, and shock absorption for neutral runners as well as those with low or high arches whose feet rolled inwards during footstrike. The firmer foam helped reduce the roll. The Lunarglide+ 4 is different. The soft Lunarlon foam is not restricted to the firm foam cavity. Nike has placed the soft foam on top of the firm midsole as a separate piece. The diagonally linked foams offer greater pronation control. The larger soft Lunarlon foam piece also adds to the cushioning and shock absorption. However, I am concerned about the way the heel rolls to the side. The exact impact of this on overall gait transition after prolonged use needs to be determined.
The Nike Lunarglide+ 4 also wins me over with its additional cushions which feel like a spring and prevent the foot from destabilizing. The shoe uses multiple side cords in the midsection add pressure on the sides of the foot. The shoe retains the perfect glove fit of the +3 model. I felt that the upper section of the shoe snugged my toes well, may be because of the Flywire cords. The single layer mesh on the upper surface feels great. It allows different sizes of vents which helped me keep cool in real hot weather as well.
The reduced rubber covering on the outsole of the new Nike Lunarglide+ 4 has helped reduce the weight of the shoe significantly. I also felt that the shoe was more flexible, mainly due to the deep flex groves in the midsection of the shoe. The molded sockliner, padded collar, and the molded heel clip are similar to what you would see in Lunarglide+ 3.
Nike Lunarglide+ 4 is definitely a great shoe for neutral to mildly overpronating runners. Tighter lacing may help improve the performance of the Flywire cord system. If you are still uncomfortable, try avoiding the flywire laces completely.
