I have used these on several rides this Summer in 90+ degree weather. Airflow is great and keep my feet comfortable. Protection seems good and to be in the right places. These boots seem to be solidly built. They are a little stiff but that can be expected for the protection they offer. Great boot- I absolutely love mine.
Sidi Fusion Air Boots
I ordered these without trying a pair on. I have Sidi off road boots which fit very well, so I ordered the Fusions in the same size. I was a little alarmed by the snug fit at first, but with thinner socks they're fine.
These are my first real street boots. I have always worn work boots. So I was a little concerned about control sensitivity. I needn't have worried these feel great on the bike. They're so light, and feel nimble! They ventilate very well.
I haven't worn them on a long ride yet, so I'm looking forward to the trip to Laguna Seca later this month.
