Speed Instinct is a fast and nimble trail shoe form Hoka, although it doesn’t look like the typical bulky Hoka shoe with big midsole. Speed Instinct is a neutral shoe with weight of 8.6 oz without the insole for size 10 and a half, with stack height of 25 mm in the heel and 22 in the forefoot which makes a 3 mm heel to toe drop. More drop is for most perceived as more comfortable. Less drop is more like the natural position of the foot, but it also puts more strain on the muscles and tendons of the foot. Speed Instinct is uptempo / racing shoe where less drop is recommended.
