All the Powerslide boots are built around the same good last design. The difference between the R1, R2 R3 and R4 is the R1 has a carbon shell which makes the boot lighter and comes with a buckle, the R2 has a plastic shell (which works just fine for me) and a buckle and the R3 has a plastic shell with no buckle and the R4 is a higher cut plastic shelled boot. There really is no need for 4 different reviews for these 4 different boots as they are all tailored around the same good last design but each one has different options. Again just checking to see if the last that this boot is built around is the same as the last the R3 is built around and yes this boot performed well just like the R3. Please look at the R3 review as all that applies to the R3 applies to the R2. The difference between the R2 and the R3 is the R2 has a buckle and is a different color. One difference I did notice is the R3 was 14 ozs and the R2 was 17 ozs. If weight is an issue the R3 would be the best choice but you don't get a buckle. There's not much for me to say, if a boot performs well and is comfortable there's not much more to write about it. (continued below)
