Ive been in gymnastics for 13 years but recently decided i was going to try out for my high school cheerleading squad in april... i can tumble really good but its bare foot =[ now i have to wear shoes... well i was planning on going to a place tonight that kinda helps with cheer tumbling but my problem is i dont have shoes... are these ok. http://www.kohls.com/kohlsStore/shoes/womens/athletic/PRD~300169/new+balance+645+Running+Shoes.jsp also how much diffrent is it to tumble in shoes?
