 uh footwear i should say and so it's got really no tread on the bottom so they were also making sure they had good footing getting over but you're right i mean this is so difficult as a pit crew member to not only execute a really good stop but to do it in these kind of conditions and also don't forget several drivers came in under that caution still having slick tires on so try not to overshoot your pit box as well was something that they were really critical of so so far on my end of pit road everybody executed just fine
