Im a big guy ~250. My knees cant take planting... I am 49 and have been bowling 35 years competitively. Today approaches kill me, especially when there is humidity outside.
I have used those cheap slide socks and found the to be like ice. So I noticed Smash49 signature and gave them a try. I ordered one and have used it now in all three houses I bowl for two weeks. All I have to say is "consistancy". Others have problems... and I dont. I got the best one, with the side edges for like 10.99 and 2 for shipping or so. THE BEST INVESTMENT i have ever made, period, in my bowling.
My only complaint was that it took over almost two weeks for delivery. They said they had a big order or something. Maybe they did but for me I am buying another one to keep as a spare.
