I have the same issue with the SST8s so I switched to the 3G. My main issue was that I went thru 3 push soles in 4 months. The 3G have a large toe guard then seemed to make the difference. Since that time, Dexter came out with a toe guard for the SST8. Next pair of shoes will probably be 3G, SST6 or SST8 with the additional toe guard.
