Forma Phantom Flow Boot

We tried on a selection of Forma boots here in the office and found the length to be about right. The width on the boots is a touch more wide than most other brands we carry. Alpinestars and TCX tend to be the most wide, but these might even be a touch wider. I’d say they are a D to E and might even work for somebody with a slightly wider foot (but don’t get carried away and think they are wide enough for a person needing a EEE or wider). So my advice would be to use the chart below to choose a size based upon your US shoe size.

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.
