They're no good in cold weather, so after one of the coldest winters on record, it was just bearable enough for a run around the complex without shoes.  It was a bit cumbersome to get them on, but they didn't require relacing.  The right foot was looser than the left foot, but there was no issue with either coming off.  The left tightness & toe knots were irritating.  By 1/4 mile, both feet slid forward 1" until the toes were overhanging. 

Would say the toe knot was a failure & the heel needed to be 1" farther back.  Just need 1 forecast to be right this year & the weather to stay above suicidal for more than 3 hours, but the forecasts have all been off.
