I have shoes from sidebike (model 028) with carbon soles und 2 boa style mechanism. Im happy with the shoes especially as i only paid 130 Euro for them.
I wanted to buy a pair this summer from santic but ther prices double and are nor more interesting. Last year the shoe i wanted was sold for 145 with coupouns and now it costs 288

.
So at the moment i'd rather go with sidebike.
