micoach is all you need to get the results you want.
The boost is cool and it's more comfortable than similar shoes, for example Nike victory elites are what I usually race in. If adidas keeps making shoes of this quality I will continue to get them. The color is awesome too. I'm sick of seeing bright neon colored shoes and shoes with lots of different color. Adidas is good at making a good looking shoe
I wear a size 7 in my adidas trainers (Adizero Boston Boost) and bought a size 6.5 in these spikes. They fit perfectly! I like my spikes to be a bit more snug so that a form fitting without squishing my toes or being to tight in any places. When I first took these out of the box I was worried becasue they didn't look aggressive enough to force me up on my toes but after working out in them I found out that they were great! This distance spike has a durable sole which is great for cross country and longer events on the track. I am very pleased!
I am very Like the style but there is so terible when I walk on the wood / title / carpet floors. It makes noise like the horse's foot with the iron nails I tried to remove them out (the iron nails) then I slipped and fell on the carpet & wood floors I've bought it since 2 weeks ago but I cannot wear it outside :(
