Bottom line, " I'll keep this one"
"Good shoe for the value. Boa works as it is designed. However, the binding strap seems to be non functional - with respect to providing additional tightening and support. Result is lots of room and no snugness causing my feet have some minor float/slopiness when pedaling. Could be a sizing issue. I've tried 44 and 45 in the RC 300 series which neither were a good fit. So I moved up to RC502. Bottom line, this will work for my current cyling regimen - cardio riding 48- 75 miles a week."
