Nike ZoomX Vaporfly Next%2 Women’s Running shoes - size 7.5 - gently worn Outside miles/km - I did a 10k race where I slammed my PR and Indoor miles ~7 mi total I absolutely love these shoes but the size is true to size and I would like to go a half number higher, I like the looser feel on my feet. Additional description of the shoes is listed below: The Nike ZoomX Vaporfly NEXT% 2 Ekiden is the next evolution of speed for reaching new goals and records, from 10Ks to marathons.Reinforcement has been used along the forefoot to provide increased durability and comfort as you go.The lacing system ensures midfoot support so you can enjoy distraction-free strides plus, an updated lace loop eliminates the need for an arch band-helping to reduce weight and relieve pressure on the top of the foot. Ultra-light and super-responsive, the midsole material delivers Nike's greatest energy return yet; it absorbs impact and then expels it back out for a bounce-like effect. Embedded within the generous ZoomX platform, and complimenting its responsive nature, is a full-length carbon fibre plate. Intended to minimise energy loss during toe bend without increasing demand on the calf, it springs up under your heel as you stride forward, yielding the snappy, propulsive sensation that converts into extra-energised strides. It's this fusion of two contrasting technologies that results in the dynamic, power-infused Vaporfly Next%, one of the most efficient marathon shoes that Nike has ever sold.
