Very true, just got in from a ride, was SPD clipped in made a tight turn front wheel slid out and now have a couple tender ribs to remind me. Had I used the bike with studs it would have been a non-issue or free legs to soften the fall at least. This happened once before about 3 years ago the locked in feet made me feel helpless. I did not clip back in the remainder of the ride home and little loss of confidence maybe.
