Looked all over for about 3 years, renting and trying friends boots and nothing worked for my duck like feet. Thought I would have to give up snowboarding because in order to get a boot wide enough for my feet the boot would have to be too long...the toe would drag and the heal would lift and I had no control.
So glad I got the Synapse wide!
This is my second year in the boot and it is perfect.
Wide in the forefoot, but still a great fit in the heal.
I really appreciate the material in the heal that grips so well, but does not irritate you. I love how you can tighten the lower part differently from the upper part, works so well! Also the lacing system is very reliable, never had a problem with the boots getting loose.
The Synapse Wide fit so well I wear them for snowshoeing too. Great boot. Very durable.
FYI I usually wear a US9.5 (2E or 4E) and the 9.5 US size (27.5 CM) Synapse wide were perfect.
