I'm into powerlifting. I competed last year, and I've been handling/volunteering this year. I'll be at the APU Provincials as a spotter/volunteer.
For SW, I'd recommend
Evolve Seton. This is where the APU provincials will be held this year (June 9-11). I don't know the drop in rates, but you can do something like $26 biweekly? Typically for deadlifting shoes, I buy from
Inner Strength Products out of... I want to say Moosejaw? Personally I do all 3 lifts in Notorious Lift slippers. However if you want to pick up something while you're here without ordering online, I'd suggest
StrongArm Sport. I don't know what they have for shoes, but they carry all the other goodies, like singlets, belts, wrist wraps, and knee sleeves.
