The Kalenji Middle-Distance Trainers with spikes is a perfect track shoe both for trainings and competitions. This was my first track shoes that I wore and I really enjoyed using it. The shoes are very lightweight and weighs about 130 grams. These shoes are also very responsive because of it's thin plate at the forefoot area. The shoes are perfect for middle distance events like 800m to 1500m but you can also use it in sprint distances. If you are finding a budget friendly but also a cool lightweight spikes, these are the ideal shoes that you need to buy.
