The Ice Pro (and Ice Pro Flow boots) fit more snugly than other Forma boots, and in our judgement, they fit about one size size small as compared to other European sized boots. We think the width is “medium” or C/D. So my advice would be to use the chart below to choose your European size based on your US shoe size, and then buy one European size bigger than the chart indicates. Same advice goes for using Forma’s foot sizing advice mentioned below…. whatever size you determine by measuring, choose one size bigger.
Forma offers advice on choosing a size from your foot measurement. Here’s how:
1) Measure the overall length of your foot. Forma recommends placing your heel against a wall and measuring from the wall to the end of your longest toe.
2) Add 3/4” to the length of your foot
3) Using Forma’s sizing chart below, choose the smallest size boot with an insole measurement that is at least the length of your foot plus 3/4”.
Use Forma’s size selection method as a “second opinion”. Maybe you’ll find it reassuring if it matches your size choice based on street shoe size or, maybe it could be a tie breaker if you are undecided between two sizes. FWIW, Forma’s advice didn’t work for me since I have relatively short toes. I wear a 45 (known from trying on) and this method put me in a 42.
