I run Scarabs and Freerider Pros on the trail bike. Daggas and Impacts on the big/trip bike. Quite happy. The Impacts are noticeably boxier, wider, and higher volume than the Freeriders. Like them for what I use them for, but not sure I'd want to use them for anything besides winch and plummet riding.
I'm a size 11.5 and it's probably what I'm used to, but the I've used the Impacts and Scarabs together once, and the combo felt weird. It felt like a lot more shoe was hanging over the outside edge of the pedal.
The Freeriders fit my foot and pedal well, and I'm quite happy. With the Scarabs, I take the washers out from under the pins about 3/4 of the way through the year. Get about a year out of a pair. On a cycle where I buy the new pair on sale during the late fall or early winter.
Feels wasteful to bin the shoes. I try my best to me environmentally conscious in as many areas of my life as possible. Have made my peace with being a little selfish on this decision.
